Question

4 целых 1/9+3/5
7 целых 3/8-5/6
1 целая 1/5: на 5 целых

Answer 1

$4 \frac{1}{9} + \frac{3}{5} = \frac{37}{9} + \frac{3}{5} = 4 \frac{32}{45} \\ \\ 7 \frac{3}{8} - \frac{5}{6} = \frac{59}{8} - \frac{5}{6} = 6 \frac{13}{24} \\ \\ 1 \frac{1}{5} \div 5 = \frac{6}{5} \times \frac{1}{5} = 0.24$
