Question

Meiling had 1 1/4 liters of juice. She drinks 1/3 of the liter.How much juice dose she have left?

Answer 1

Meiling had 1 1/4 liters of juice

Total amount of juice = 1 1/4

Express mixed fraction into standard fraction:

$\begin{gathered} 1\frac{1}{4}=\frac{1\times4+1}{4} \\ 1\frac{1}{4}=\frac{5}{4} \end{gathered}$

So, Total amount of Juice = 5/4

She drinks 1/3 of the liter i.e.

$\frac{1}{3}\times\frac{5}{4}=\frac{5}{12}$

She drank = 5/12 liter.

So, the amount of juice left : 5/4 - 5/12

$\begin{gathered} \frac{5}{4}-\frac{5}{12}=\frac{15-5}{12} \\ \frac{5}{4}-\frac{5}{12}=\frac{10}{12} \\ \frac{5}{4}-\frac{5}{12}=\frac{5}{6} \end{gathered}$

The amount of juice left = 5/6
