Four application problems in fifth grade mathematics (when the master comes, write down the main process, and add 50 points for good ones)
(1) There are as many sports shoes in two cartons as in 1 wooden cases, so two wooden cases are equivalent to four cartons, which together equals 10 cartons.

2×2=4

4+6= 10

300÷ 10=30 (30 pairs in a carton)

30×2=60 (60 pairs in a wooden box)

(2)

(22×1.51+20×1.55) ÷ (22+20) = 64.22 ÷ 42 ≈1.53 (m)

Remember the principle of averaging: the average can no longer be averaged.

You must find the total height of all boys and girls, and then divide it by the total number of people.

(3) 89×5-87×4= 97 (points)

The difference between the two total scores is the fifth score.

(4) Find the average score and compare.

Level 1: 4440÷48=92.5

Category II: 4590÷50=9 1.8

So the grade of Class One is better.
