Harold gave 1,400 stamps to his brother and sister. He gave 350 stamps to his brother. What percent of stamps did Harold give to his brother.

The percent represents the number of stamps that Harold gave to his brother out of all the stamps.

To find what percent of stamps that Harold gave to his brother, we can change the fraction to a percent.

We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 350 and 1400 using 350.

350 ÷ 350 = 1

1400 ÷ 350 = 4

Our reduced fraction is .

1 ÷ 4 = 0.25

0.25 × 100 = 25%

Therefore, Harold gave his brother 25% of his stamps.
