Question

помогите решить!!!пожалуйста

3/8*5+5/56-1/7:1/5=

Answer 1

$frac{15}{8}+ frac{5}{56}- frac{5}{7} = frac{15*7+5-5*8}{56} = frac{35+5-40}{56}=0$

Answer 2

3/8 * 5 + 5/56 - 1/7 : 1/5 = 1.25 
=============================================================
1) 3/8 * 5 = 15/8 
2) 1/7 : 1/5 = 5/7 
3) 15/8 + 5/56 - 5/7 = ( 105 + 5 - 40) / 56 = 70/56 = 35/28 = 1 7/28 = 1 1/4 = 1.25
