Subtract: 3/4 - 4/8

Question

Simplify the answer if possible.

Answer 1

To subtract fractions, we need to have a common denominator.

The denominators are 4 and 8. The least common multiple of 4 and 8 is 8.

Therefore, we need to convert both fractions to have a denominator of 8.

Converting 3/4 to a fraction with a denominator of 8:
3/4 * 2/2 = 6/8

So, 3/4 = 6/8.

Now we can subtract the fractions:

6/8 - 4/8 = 2/8

Simplifying the fraction, we can divide the numerator and denominator by their greatest common divisor, which is 2.

2/8 ÷ 2/2 = 1/4

So, 3/4 - 4/8 simplifies to 1/4.
