Answer 1

Explicație pas cu pas:

5 × 19/20

simplificam 5 cu 20

= 19/4

4×15/18

simplificam 4 /18 , dar 18 nu se imparte cu 4 deci simplificam 2

=2×15/9

=30/9

simplificam 30/9 , dar 30 nu se imparte cu 9 deci simplificam 3

=10/3

1/2×5/6=5/12

7/8×9/14

1/8×9/2=2/72 = 1/36

1 intreg 3/4 × 2 intregi 1/5

1 intreg 3/4 = 1×4+3/4=7/4

2 intregi 1/5 = 2×5+1/5=11/5

=7/4 × 11/5 = 77/20

2 intregi 4/9 × 3 intregi 1/11

= 22/9 × 34/11

=2/9×34/1

=68/9
