Answer 1

7 - 1$frac{4}{5}$ × ( 1$frac{1}{4}$ + $frac{1}{12}$ ) : 3 = 6$frac{49}{64}$
1) 1$frac{1}{4}$ + $frac{1}{12}$ = $frac{5}{4}$ + $frac{1}{12}$ = $frac{15}{12}$ + $frac{1}{12}$ = $frac{16}{12}$
2) 1$frac{4}{5}$ × $frac{16}{12}$ = $frac{9}{5}$ × $frac{16}{12}$ = $frac{15}{64}$
3) $frac{15}{64}$ : 3 = $frac{15}{64}$ × $frac{1}{3}$ = $frac{5}{64}$
4) 7 - $frac{5}{64}$ = $frac{448}{64}$ - $frac{5}{64}$ = $frac{443}{64}$ = 6$frac{49}{64}$
