Question

В)(14/27+21/27):5 Г)125/76:( 3 в верху 2 +4 верху2)

Answer 1

В) $( \frac{14}{27} + \frac{21}{27}) : 5 = \frac{14+21}{27}:5 = \frac{35}{27} :5 = \frac{35*1}{27*5} = \frac{7}{27}$

г) $\frac{125}{76} : (3^2 + 4^2) = \frac{125}{76} : (9 + 16) = \frac{125}{76} : 25 = \frac{125*1}{76*25} = \frac{3}{76}$

Удачи!
