Question

C) 3/8+1/6 d) 9/10-1/4

Answer 1

Resposta:

c) 13 / 24

d) 13 / 20

Explicação passo-a-passo:

c)

$\frac{3}{8} + \frac{1}{6} = \frac{3 \times 3}{24} + \frac{4 \times 1}{24} = \frac{9}{24} + \frac{4}{24} = \frac{9 + 4}{24} = \frac{13}{24}$

d)

$\frac{9}{10} - \frac{1}{4} = \frac{9 \times 2}{20} - \frac{1 \times 5}{20} = \frac{18}{20} - \frac{5}{20} = \frac{18 - 5}{20} = \frac{13}{20}$
