Question

Вычислите 1)13/24 + 7/10
2)1(целая) 4/15 + 3(целых) 7/25
3)9(целых) 11/12 - 5(целых) 3/8

Answer 1

$frac{13}{24} + frac{7}{10} = frac{65 + 84}{120} = frac{149}{120} = 1 times frac{29}{120}$
$1 times frac{4}{15} + 3 times frac{7}{25} = frac{4}{15 } + frac{21}{25} = frac{83}{75} = 1 times frac{8}{75}$
$9 times frac{11}{12} - 5 times frac{3}{8} = frac{33}{4} - frac{15}{8} = frac{51}{8} = 6 times frac{3}{8}$

Answer 2

1. 149/120
2. 83/75
3. 51/8
