Please need help with this

Answer 1

Explanation:

blue(b)=13

yellow(y)=12

total(b+y)=25

percentage of blue marbles=13/25 ×100

=13×4

=52%

Answer 2

The fraction
`(13)/(25)` represents the number of blue marbles in the bag out of all the marbles in the bag.

To find what percent of the marbles in the bag are blue, we can turn the fraction
`(13)/(25)` into a percent.

To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we wanted to write
`(13)/(25)` as a percent, we need to find a fraction equivalent to
`(13)/(25)` with a 100 in the denominator. We can do this by setting up a proportion.

`(13)/(25)` =
`(n)/(100)`

25n = 1,800

÷25 ÷25

n = 52%

Therefore, 52% of the marbles in the bag were blue.
