Question

a)3/8÷9/2= b)7/15÷14/5 c)4intregi1/3÷26/7 d)28/3÷5intregi1/4​

Answer 1

3/8 : 9/2 = 3/8 × 2/9 = 1/4 × 1/3 = 1/12

7/15 : 14/5 = 7/15 × 5/14 = 1/3 × 1/2 = 1/6

4 întregi 1/3 = ( 4 × 3 + 1 )/3 = ( 12 + 1 )/3 = 13/3

13/3 : 26/7 = 13/3 × 7/26 = 1/3 × 7/2 = 7/6

5 întregi 1/4 = ( 5 × 4 + 1 )/4 = ( 20 + 1 )/4 = 21/4

28/3 : 21/4 = 28/3 × 4/21 = 4/3 × 4/3 = 16/9
