Question

7 5/8+2 2/3 - 4 3/16​

Answer 1

$7 \frac{5}{8} + 2 \frac{2}{3} - 4 \frac{3}{16} = 7 + \frac{5}{8 } + 2 + \frac{2}{3} - 4 - \frac{3}{16} = 5 + \frac{53}{48} = 5 + 1 + \frac{5}{48} = 6 \frac{5}{48}$

Answer 2

Ответ:

$7\frac{5}{8}+2\frac{2}{3}-4\frac{3}{16} = 7+\frac{5}{8}+2+\frac{2}{3}-(4+\frac{3}{16})= \\\\=7+\frac{5}{8}+2+\frac{2}{3}-4-\frac{3}{16}= (7+2-4)+(\frac{5}{8}+\frac{2}{3}-\frac{3}{16})=\\\\=5+(\frac{30+32-9}{48})= 5+\frac{53}{48}=5+1\frac{5}{48}=5+1+\frac{5}{48}=6\frac{5}{48}$
