Proportion Question What is the proportion? Explain why. Fast!!! Good plus bounty!!!!!!!

1.Disproportionate lack of constant quantity. 2.

Disproportionate It doesn't matter 3Proportionally, the larger the radius, the larger the area, and vice versa, the smaller the radius, the smaller the area4Disproportionate because it is not a one-step multiplication and division of 5

It is proportional because the more distance you make, the more time you take, and vice versa.

6.Disproportionately unchanging amount7proportional because the more time you have, the more time you have, the less time you have, the less you do.8

The proportional ratio is the same as above question 9Disproportionately absent constant amount10Disproportionately absent invariants 11

Proportional, inversely proportional 12Inversely proportional, the faster the speed, the less time, the less time, the more time13Inversely proportional, because the circumference of the bottom surface is higher than the side area, the side area is certain, so it is inversely proportional 14

Inversely proportional to the common sense of life, the higher the pole, the shorter the shadow.15The proportional denominator is larger, and the larger the proportional divisor, the larger the quotient, and the inverse proportional. 16.

Disproportionate addition and subtraction cannot be proportional 17Disproportionate has nothing to do with 18The circumference of is equal to the diameter or the radius multiplied by 2 and the two-step calculation cannot be proportional to 19

Addition and subtraction are disproportionate20Proportional: Suppose x is 5y, is 4, the result is 20, but the larger the x, the greater y must also become, the x becomes smaller, the proportional assuming a is 1, b is a, 2 b, so proportional, assuming x is 1, y is x, 2 y, so proportional, quarters x 5/y, assuming x is 5, y is 4, so it is proportional, and x of 4 is equal to 5/y, proving that y is multiple times greater than x, so it is proportional, and the quarter x is 5/5 y, assuming that x is 5 y, proving that y is multiple times greater than x.

Multiple choice question 1Choose d because 2 2 equals 4 equals 5 and is the same multiple of them 2d 3/10 becomes a ratio in the form of 3 ratios.

True/False Question 1Because any number can be composed of ratios, but (except 0) 2Zero cannot be the last 3Just practice it yourself.

The landlord saw that I was typing so hard, and offered me a reward.

You should ask your teacher.

Buy the same computer, the number of computers purchased and the total price.

The total price of the number of units = unit price (certain), in direct proportion.

The number of books in each bundle is the same, and the total number of books and bundles in the exercise books.

The total number of books in the exercise book Number of bundles = Number of books per bundle (certain) Proportional fractional value is constant, the numerator and denominator of the fraction.

Numerator Denominator = Fractional Value (Certain) Proportional.

The distance on the diagram is certain, and the actual distance is the same as the scale.

Actual distance Scale = distance on the figure (certain) In inverse proportion, the flour yield of wheat is constant, and the quality of wheat is related to the quality of flour.

The quality of the flour The quality of the wheat = the flour yield of the wheat is certain.

proportional.

Buy the same computer, the number of computers purchased and the total price. The number of books in each bundle is the same proportional to the total number of books and bundles of exercise books. The inversely proportional fraction value is a certain numerator and denominator of the fraction. proportional.

The distance on the diagram is certain, and the actual distance is the same as the scale. proportional.

The flour yield of wheat is certain, and the quality of wheat is related to the quality of flour. proportional.

Buy the same computer, the number of computers purchased and the total price. The unit price is fixed, and the number of computers is directly proportional to the total price.

The number of books in each bundle is the same, and the total number of books and bundles in the exercise books.

The number of exercise books in each bundle is fixed, and the total number of exercise books and the number of bundles are directly proportional.

The fractional value is constant, the numerator and denominator of the fraction.

The fraction value is constant, and the numerator and denominator of the fraction are directly proportional.

The distance on the diagram is certain, and the actual distance is the same as the scale.

The distance on the diagram is constant, and the actual distance is inversely proportional to the scale.

The flour yield of wheat is certain, and the quality of wheat is related to the quality of flour.

The flour yield of wheat is certain, and the quality of wheat is not proportional to the quality of flour.

1. Proportional.

2. Proportional.

3. Proportional.

4. Inverse proportionality.

5. Proportional.

The relationship between the two is dividing and proportional;

The relationship between the two is inversely proportional.

Just remember the basic nature of proportions.

The basic property of proportion: the product of two internal terms = the product of two external terms.

(1) Xiaohong: Xiaoliang is 2:3

Xiao Liang: Xiao Gang is 3:4

Xiaohong: Xiaoliang: Xiaogang 2:3:4, Xiaohong: Xiaogang 2:4 1:2(2)8+4 8+8 2 8 3 2

Question 1: 36 (2-1) = 36 (yuan) -- **36 + 36 = 72 (yuan) -- mobile phone.

The second question is set to A = 1

A: B=1:2 then B=2

B: C = 2:1 then C = 1

C: D = 2: 3 then D =

D: E = 1:2 then E = 3

So E is the largest, and A and C are the smallest.

Question 3 10 [ 4 5)- 7 12)] =600 13

X who teaches Chinese teaches y of mathematics

x/y=13/7

x-2/y+2=3/2

Solve the second problem y=14 x=26.

Question 3. A has x copies.

B has a y copy. x/y=4

x/4=20

x=80 y=20

Inversely proportional, multiplication is constant.

Here the total number of copies = unit price.

That is, division is constant.

So it's proportional and not inversely proportional.

Base height = area 2 is a constant.

So it's inversely proportional.

In the ratio, (ratio) is certain, (the former term) is (positive) proportional to the (posterior);

The latter term) is certain, and (the former term) is (positively) proportional to (ratio);

The former term is certain, and the (latter term) is (inversely) proportional to (ratio).

There are 5x for boys and 3x for girls

It is 2y for boys and 2y for girls

The vertical equation is 5x+2y=32

3x+y=18

Solution: x=4, y=6

Therefore, the female students in the kindergarten class are 3x=3*4=12

The number of large classes is x and the small class is y

then there is x+y=32+18

5/8)*x+(2/3)*y=32

In the same way, you can also figure out a formula and solve it yourself.

The answer is 3 8x
