Answer 1

Given:

Total no. of marbles in the box = 25

No. of green marbles = 10

No. of blue marbles = 15

To find:

The fraction of green marbles and blue marbles

Solution:

Using the given data, we will calculate the fraction of green and blue marbles:

∴ The fraction of green marbles is,

= $\frac{No. \:of\:green \:marbles\: in\: the\: box }{Total\:marbles\:in \:the\:box}$

= $\frac{10}{25}$

= $\frac{2}{5}$

and

∴ The fraction of blue marbles is,

= $\frac{No. \:of\:blue \:marbles\: in\: the\: box }{Total\:marbles\:in \:the\:box}$

= $\frac{15}{25}$

= $\frac{3}{5}$

Thus, the fraction of green marbles is $\underline{\bold{\frac{2}{5}}}$ and blue marbles is $\underline{\bold{\frac{3}{5}}}$.
