Question

(7-4 3/4)*1 1/3+(6-4 2/5)/1 1/3

Answer 1

= 2 1/4 * 1 1/3 + 1 3/5 * 3/4 = 9/4 * 4/3 + 8/5 * 3/4 = 3 + 6/5 = 3 + 1 1/5 = 4 1/5

Answer 2

$1)7-4 \frac{3}{4} =2 \frac{1}{4} \\ 2)2 \frac{1}{4} *1 \frac{1}{3} = \frac{9}{4} * \frac{4}{3} =3 \\ 3)6-4 \frac{2}{5} =1 \frac{3}{5} \\ 4)1 \frac{3}{5}:1 \frac{1}{3} = \frac{8}{5} : \frac{4}{3} = \frac{8}{5} * \frac{3}{4} = \frac{6}{5} =1 \frac{1}{5} \\ 5)3+1 \frac{1}{5} =4 \frac{1}{5}$
