Question

4 ЦЕЛЫХ 2/7:5/14:0,2-0,2*1,4

Answer 1

$4frac27:frac5{14}:0,2-0,2cdot1,4=frac{4cdot7+2}7:frac5{14}:frac2{10}-frac2{10}cdotfrac{14}{10}=\ =frac{30}7:frac5{14}:frac15-frac15cdotfrac75=frac{30}7cdotfrac{14}5:frac15-frac7{25}=\ =6cdot2:frac15-frac7{25}=12cdot5-frac7{25}=60-frac7{25}=59frac{18}{25}=59frac{72}{100}=59,72$
