Franklin saved money to buy art supplies

Nikolay [14]

<u>Question</u>:

Franklin saved money to buy art supplies. He used 1/5 of his savings to buy brushes. He used 1/2 of his savings to buy paint. What fraction of his savings does he have remaining?

Answer:

Franklin had $\frac{3}{10}$ of his saving left.

Step-by-step explanation:

Amount used to buy brushes = 1/5

Amount used to buy paint = 1/2

Solution:

Let the remaining amount be x

then ,

x = 1- (amount used on buying brushes + amount used for buying paints)

$x = 1- (\frac{1}{5} + \frac{1}{2})$

$x = 1- (\frac{2+5}{10})$

$x = 1- (\frac{7}{10})$

$x =\frac{10-7}{10}$

$x =\frac{3}{10}$
