Question
Solve the following equation for the unknown: $\frac{4 x}{27}=\frac{8}{9}$
✓
Answer
$\frac{4 x}{27}=\frac{8}{9} $
$ \therefore(4 x)(9)=(8)(27)$
$ \therefore x=\frac{8 \times 27}{4 \times 9} $
$\therefore x=\frac{2 \times 3}{1 \times 1}$
$ \therefore x=6$
$ \therefore(4 x)(9)=(8)(27)$
$ \therefore x=\frac{8 \times 27}{4 \times 9} $
$\therefore x=\frac{2 \times 3}{1 \times 1}$
$ \therefore x=6$
