Question

6) 3целых 6/7*7.6-2.06*3целых 6/7-7.4*3целых 6/7​

Answer 1

$3 \frac{6}{7} \times 7.6 - 2.06 \times 3 \frac{6}{7} - 7.4 \times 3 \frac{6}{7} = 3 \frac{6}{7} \times (7.6 - 2.06 - 7.4) = 3 \frac{6}{7} \times ( - 1.86) = - \frac{27 \times 93}{7 \times 50} = - \frac{2511}{350} = - 7 \frac{61}{350}$
