Question

( 3,6-1 2/3)/(4 1/15- 2 7/9)*2,6

Answer 1

Ответ:

( 3,6 - 1 2/3) ÷ ( 4 1/15 - 2 7/9 ) × 2,6 = 1/6

1) 3,6 - 1 2/3 = 3 6/10 - 1 2/3 = 3 3/5 - 1 2/3 = 3 9/15 - 1 10/15 = 2 24/15 - 1 10/15 =  1 14/15

2) 4 1/15 - 2 7/9 = 4 3/45 - 2 35/45 = 3 48/45 - 2 35/45 = 1 13/45

3) 1 13/45 × 2,6 = 58/13 × 1 3/5 = 58/5 = 11,6

4) 1 14/15 ÷ 11,6 = 29/15 ÷ 11 3/5 = 29/15 ÷ 58/5 = 1/6
