Amanda cut a piece of wood that was 10/12 of a yard long. She used 3/4 of the wood how many yards of wood were left over

Nadya [2.5K]

The wood is 10/12 yard long.

She used 3/4 of the wood:
$\dfrac{3}{4} \times \dfrac{10}{12}$

$\dfrac{3}{4} \times \dfrac{2 \times 5}{3 \times 4}$

$\dfrac{3}{8} \text { yard}$

Calculate yards left:

$\dfrac{10}{12} - \dfrac{3}{8}$

$= \dfrac{20}{24} - \dfrac{9}{24}$

$= \dfrac{11}{24} \text { yard left}$
