Answer 1

$\frac{4}{9}*( 1\frac{1}{2}c- \frac{3}{8})-(1 \frac{5}{6}- 1\frac{1}{3}c)= \frac{12}{18} c- \frac{12}{72}-1 \frac{5}{6}+ 1\frac{1}{3}c= 2c-1 \frac{2}{3}$
1) $\frac{12}{18}c+ \frac{4}{3}c= \frac{12+24}{18}c = \frac{16}{18}c=2c$
2) $- \frac{12}{72}-1 \frac{5}{6}= -\frac{12}{72}- \frac{11}{6} = \frac{-12-132}{72} = \frac{120}{72}= \frac{60}{36}= \frac{10}{6}= \frac{5}{3}=1 \frac{2}{3}$

Answer 2

I can help you with simplifying expressions. Here is the answer:

$$\frac{4}{9}\left(1+\frac{1}{2}c-\frac{3}{8}\right)-\left(1+\frac{5}{6}-1-\frac{1}{3}c\right)$$

$$=\frac{4}{9}\left(\frac{8+4c-3}{8}\right)-\left(\frac{5-3c}{6}\right)$$

$$=\frac{4}{9}\left(\frac{4c+5}{8}\right)-\frac{5-3c}{6}$$

$$=\frac{4}{9}\cdot\frac{4c+5}{8}-\frac{5-3c}{6}$$

$$=\frac{4c+5}{18}-\frac{5-3c}{6}$$

$$=\frac{4c+5-15+9c}{18}$$

$$=\frac{13c-10}{18}$$

This is the simplest form of the expression.Ответь+подробно.+Упростите+выражения+4/9(1+1/2с-3/8)-(1+5/6+-+1+1/3с)
