Question

помогите пожалуйста !!!

Answer 1

$((1frac{1}{4})^2-frac{5}{8})*10frac{2}{3}-7frac{1}{3}=((frac{5}{4})^2-frac{5}{8})*frac{32}{3}-7frac{1}{3}= \ =(frac{25}{16}-frac{5}{8})*frac{32}{3}-7frac{1}{3}=(frac{25}{16}-frac{10}{16})*frac{32}{3}-7frac{1}{3}= \ =frac{15}{16}*frac{32}{3}-7frac{1}{3}=5*2-7frac{1}{3}=10-7frac{1}{3}=9frac{3}{3}-7frac{1}{3}=2frac{2}{3}$

Answer 2

(25/16-10/16)*32/3-22/3=15/16*32/3-22/3=30/3-22/3=8/3
