Write two division formulas according to multiplication formula
First course: 1 / 5 × 3 = 3 / 5
Second: 3 / 5 × 4 / 7 = 12 / 35
Note: it's a two-way division
Three fifths divided by one fifth is three
Twelve out of thirty-five divided by three out of five equals four out of seven
In the judgment question, only one multiplication formula can be calculated with one multiplication formula
×
Every formula can write two division and two multiplication, right
Yes
For example: 3824
3×8=24
8×3=24
24÷8=3
24÷3=8
