Which is a 6th grade math problem!?

It's easy. I'm also an elementary school student, and I'm here to help you

300 60 = 5 hours (time spent on the motorcycle) 435-300 = 135km (the road taken by the motorcycle) 135 45 = 3 hours (time spent on the motorcycle) 5-3 = 2 hours (late time) Answer: 2

1-40% = 60% (120 copies corresponding to the score) 120 60% = 200 copies (a total of 200 copies) 200-185 = 15 copies (15 copies are the 1350 copies) 1350 15 = 90 sheets (90 sheets each) 200 * 90 = 18000 sheets.

Answer: 18000

Let's start with the answer haha: inverse ratio. If you do it, you'll find that this algebraic formula: 3 2=x*y, so it's inversely proportional

Answer: x:y=7:3

Do you write 2 steps to see? I don't know what to say, but I know it at a glance.

Answer: 2 (1+1 10) = 20/11

Just pull me I still have English questions to help me with I am good at math, and I have questions to ask me, if my answer is accidentally wrong, then I'm sorry to pull! Me, right?

Thank you

3 Inverse proportionality.

5 The volume after dissolution is x

1+1/10)x=2

x=20/11

1.The time the car travels is 300 60 = 5 hours.

The distance traveled by the motorcycle at the time of the encounter: 135 km

The time of the motorcycle is: 135 45 = 3 hours.

So the motorcycle was 2 hours late.

2.If 120 books have been bound and the remaining paper is 40% of this batch of paper, then 120 books account for 60 of the total, then the total number of bound copies is: 120 (60%) = 200, if 185 books are bound, there are 1350 sheets of paper left, so that 200 185 15 books are 1350 sheets of paper.

Then one book is 1350 15 = 90, so the total number of sheets is: 200 90 18000 sheets.

3.Anti. 4.There's something wrong with the problem, and the condition isn't an equation, so it can't be calculated.

5.I forgot if I learned equations in the sixth grade, and if I did, the upstairs was right.

Well, the landlord, it said that the harvest of each experimental field this year is compared with last year, that is, the increase in yield + negative yield of each piece = the total yield of this year's rice experimental field and the value of last year (58kg + 38kg = increased yield, -42kg + -8kg + -16kg = negative yield, increased yield + negative yield = 30kg, so choose b, I hope to help you.

A section of the road, a wheel with a diameter of 80 cm travels 1000 cycles, how many weeks does a wheel with a diameter of 50 cm travel?

80 times 1000 divided by 50 = 1600 (weeks).

There is a batch of fruits, 600 kilograms are transported every day, the ratio to the mass of this batch of fruits is exactly 1:6, the quantity transported the next day is 1:5 to the quality of this batch, how many kilograms are transported the next day?

600：x=1:6

x=3600

y：3600=1:5

y=720

1. The distance traveled by the wheel should be calculated according to the circumference * number of weeks, 80 * 1000 50 = 1600

2. The total mass of this batch of fruits is 600*6=3600

The next day the remaining 1 5 was transported away, (3600-600) * 1 5 = 600

The answer is: 5 out of 138.
