4 5/8+(3 1/2-2 7/8) *4 -2 3/8=

Решите задачу:

$4\frac{5}{8}+(3 \frac{1}{2}- 2\frac{7}{8})*4-2 \frac{3}{8} \\ 1)3 \frac{1}{2}- 2\frac{7}{8}= \frac{7}{2}- \frac{23}{8} =\frac{28}{8}- \frac{23}{8}= \frac{5}{8} \\ 2)\frac{5}{8}*4= \frac{20}{8} \\ 3)4\frac{5}{8}+ \frac{20}{8}= \frac{37}{8}+ \frac{20}{8}= \frac{57}{8} \\ 4) \frac{57}{8}-2 \frac{3}{8}= \frac{57}{8}- \frac{19}{8}= \frac{38}{8}=4 \frac{6}{8}=4 \frac{3}{4}=4,75$
