Reduce this fraction to lowest terms.

fraction numerator 21 over denominator 28 end fraction

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.

To reduce a fraction to its lowest terms, we need to find the greatest common divisor (GCD) of the numerator and denominator and divide both by it.

In this case, the numerator is 21 and the denominator is 28. The GCD of 21 and 28 is 7.

Now, divide both the numerator and denominator by 7:

Numerator: 21 ÷ 7 = 3
Denominator: 28 ÷ 7 = 4

Therefore, the fraction 21/28 in its lowest terms is 3/4.

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 that GCD.

In this case, the numerator is 21 and the denominator is 28. To find the GCD, we can use the Euclidean algorithm.

Step 1: Take the larger number (28) and divide it by the smaller number (21).
28 ÷ 21 = 1 with a remainder of 7.

Step 2: Now, take the previous smaller number (21) and divide it by the remainder (7).
21 ÷ 7 = 3 with no remainder.

Step 3: Repeat step 2 until we reach a remainder of zero.
7 ÷ 3 = 2 with a remainder of 1.
3 ÷ 1 = 3 with no remainder.
1 ÷ 1 = 1 with no remainder.

Since we have reached a remainder of zero, the last divisor, which is 1, is the GCD of 21 and 28.

Now, we can divide both the numerator and denominator by the GCD to simplify the fraction:

Numerator: 21 ÷ 1 = 21
Denominator: 28 ÷ 1 = 28

So, the fraction 21/28 in its lowest terms is 21/28.
