Basic Grade 3 Math Fill in the Blank 10

Each bottle is worth 6 yuan = 240 yuan 5 boxes and 8 sticks.

Total farmland 120 hectares on this day = (4 hours in the morning + 6 hours in the afternoon) * 12 hectares per hour on average.

Question 1: 5 (box) * 8 (branches) = 40 (branches).

240 (yuan) 40 (branches) = 6 (yuan branches).

Question 2 (1st solution): 4 (hour) + 6 (hour) = 10 (hour) 10 (hour) * 12 (ha) = 120 (ha) second solution): 4 (hour) * 12 (ha) = 48 (ha) pm 6 (hour) * 12 (ha) = 72 (ha) total 48 (ha) + 72 (ha) = 120 (ha) In summary:

The combination of the first question: 240 5 8 = 6 (yuanzhi) or 240 (5*8) = 6 (yuanzhi).

The combination of the second question: (4+6)*12=120 (ha) 4*12+6*12=120 (ha).

Question 1: 5 (box) * 8 (branches) = 40 (branches).

240 (yuan) 40 (branches) = 6 (yuan branches).

Combination: 240 5 8 = 6 (yuanzhi) or 240 (5*8) = 6 (yuanzhi).

The combination of the second question: (4 + 6) * 12 = 120 (ha) The second question (one solution): 4 (hour) + 6 (hour) = 10 (hour) 10 (hour) * 12 (ha) = 120 (ha) two solutions):

Morning 4 (hours) * 12 (hectares) = 48 (hectares) 6 (hours) * 12 (hectares) = 72 (hectares) Total 48 (hectares) + 72 (hectares) = 120 (hectares) Combination: (4 + 6) * 12 = 120 (hectares).

4*12+6*12=120 (hectares).

Example: 2019 Primary 3 Mathematical Thinking Exercise: Fill in the numbers to make the equation true.

After filling in the same number in each box of equation (7) 16=2, the equation can be true, and this number can be found.

Answer Analysis]:

7 =11 -7 =11-7) = 4, because 4 16=2, so 4=32, =8

Answer: =8

In the third grade math problem, the bend refers to filling in the box of the buried matching formula.

A. What is the balance and loss B?

Solution: 1. According to observation, the single digit of the sum of this problem must be equal to b or 1b 2b 3b....i.e. b+b+b=b or b+b+b=?

b, i.e. 3 times b, must be equal to the number that is b in the single digit. Using the numbers 0 to 9, only 3 times 5 to 15 meet this requirement.

2. a+a+5=8 or a+a+5=?8, because the first step has calculated that b is 5, so here a+a+5=18Using 18-5 = 13 13 and subtracting the 1 that comes in later is equal to 12So a should be 12 divided by 2=6

3. Now take the calculated number to the equation and calculate whether it is consistent.

1.Zhang Ming's family of three used 54 tonnes of water in the first half of the year, with an average of 3 tonnes per person per month.

54 3 6 = 3 tons.

2.In a school, grades 1-6 have four classes in each grade, and there are 1,200 books to be distributed to each class, and each class can get an average of (50) books.

1200 4 6 = 50 copies.

1.A 6-storey building, divided into 4 units, each unit 1-6 floors Hengtan each lives three households, this building can accommodate (72) households.

2.Class 3 (1) has 6 teams of 7 people per group, and Zheng Sheng collects an average of 5 plastic bags per person per day, and can collect (1470) plastic bags a week.

Multiply (2) by (24) in (number) digits to get 48 (1).

Multiply (3) by (24) in the (ten) digit to get 72 (10).

Then add the two parts (add).

2 24 1

Ten 3 24 1

Add (?) It seems that this is the only way to fill in).
