c) 5/8 ÷ 2
d) 7/10 ÷ 14​

Answer 1

Resposta:

$a:\ 0,05\\\\b:\ 0,047611905\\\\c:\ 0,3125\\\\d:\ 0,05$

Explicação passo a passo:

$a)\ \frac{\frac{1}{4}}{5}\\\\\frac{1}{4}\bullet\frac{1}{5}=\frac{1}{20}=0,05\\\\ou\\\\\frac{0,25}{5}=0,05\\\\\\b)\ \frac{\frac{1}{3}}{7}\\\\\frac{1}{3}\bullet\frac{1}{7}=\frac{1}{21}=0,04761905\\\\ou\\\\\frac{0,33}{7}=0,04761905\\\\\\c)\ \frac{\frac{5}{8}}{2}\\\\\frac{5}{8}\bullet\frac{1}{2}=\frac{5}{16}=0,3125\\\\ou\\\\\frac{0,625}{2}=0,3125\\\\\\d)\ \frac{\frac{7}{10}}{14}\\\\\frac{7}{10}\bullet\frac{1}{14}=\frac{7}{140}=0,05\\\\ou\\\\\frac{0,7}{14}=0,05$
