Fraction which are red = 50/250

= 1/5

To get the percent we multiply by 100:-

1/ 5 * 100

= 100/5

= 20% answer

Riley has 250 marbles in his collection. 50 of the marbles are red.

The fraction
(50)/(250) represents the 50 marbles that are red out of all the marbles. We can find out what percent of marbles are red by changing the fraction
(50)/(250) to a percent.

The fraction
(50)/(250) can be reduced to
(1)/(5)
by dividing both the numerator and denominator by the greatest common factor of 50 and 250.

1 ÷ 5 = 0.2

0.2 × 100 = 20%

Therefore, 20% of the marbles are red.
