To reduce a fraction to its lowest terms, we need to find the greatest common divisor (GCD) of the numerator and denominator, and then divide both the numerator and denominator by the GCD.
The GCD of 21 and 28 is 7.
Dividing both the numerator and denominator by 7, we get:
21 ÷ 7 = 3
28 ÷ 7 = 4
Therefore, the fraction 21/28, when reduced to lowest terms, is 3/4.
Reduce this fraction to lowest terms.
