Question

Номер 587, пожалуйста!

Answer 1

А) (1/2 - 1/3) : 2 + 1/3 = 1/6 : 2 + 1/3 = 1/12 + 1/3 = 5/12

б) (3/5 - 4/7) : 2 + 4/7= 1/35 : 2 + 4/7 = 1/70 + 4/7 = 41/70

в)  $(2 \frac{1}{4}- \frac{5}{8}):2+ \frac{5}{8} = \frac{13}{8}: 2+ \frac{5}{8} = \frac{13}{16}+ \frac{5}{8} =1 \frac{7}{16}$

г)  $(3 \frac{1}{2}-3 \frac{1}{4}):2+3 \frac{1}{4} = \frac{1}{4}:2+3 \frac{1}{4}= \frac{1}{8}+3 \frac{1}{4}= \frac{27}{8}=3 \frac{3}{8}$
