Question

(-8 4/7)-(-66)-(-9,4)+(-1 4/25)-6 3/7​

Answer 1

$- 8 \frac{4}{7} + 66 + 9.4 - 1 \frac{4}{25} -6 \frac{3}{7} = - 15 - 1 \frac{4}{25} + 75.4 = - 15 - 1.16 + 75.4 = - 16.16 + 75.4 = 59.24$

Answer 2

-8 4/7+66+9,4-1 4/25-6 3/7=59 6/25
1) -8 4/7+66=57 3/7
2) 57 3/7+9,4=66 29/35
3) 66 29/35-1 4/25=65 117/175
4) 65 117/175-6 3/7=59 6/25

Надеюсь правильно)))
