Question

Realize os cálculos necessários e escreva a fração equivalente a:

a) 1/6, com denominador igual a 24.

b) 4/9, com numerador igual a 48.

c) 42/112, com numerador igual a 13.

Answer 1

$a)~\frac{1}{6}~com~denominador=24=\frac{4~.~1}{4~.~6}~ =\frac{4}{24}\\\\b)~\frac{4}{9}~ com~numerador=48=\frac{4~.~12}{9~.~12}=\frac{48}{108}\\\\c)~\frac{42}{112}~com~numerador=13~~~~(impossivel)$

$\frac{42}{112}=\frac{13}{x}\\\\x=\frac{112.13}{42}\\\\x=\frac{~~13~~}{\frac{1456}{42}~}$
