Answer 3

Let's break this down step by step:

1. Start with the subtraction of fractions: 3/4 - 1/8 = ?

To subtract fractions, you need to have a common denominator. In this case, the common denominator is 8. So, we need to convert both fractions to have a denominator of 8:

• For 3/4, you can multiply both the numerator and denominator by 2 to get 6/8.
• For 1/8, you don't need to change it, as it already has a denominator of 8.

Now, subtract the fractions:

6/8 - 1/8 = (6 - 1)/8 = 5/8

So, 3/4 - 1/8 = 5/8.

2. Now, you have 5/8, and you want to multiply it by 5/8 and subtract 1/2:

(5/8) * (5/8) - 1/2

To multiply fractions, you simply multiply the numerators together and the denominators together:

(5/8) * (5/8) = (5 * 5)/(8 * 8) = 25/64

So, the expression becomes:

25/64 - 1/2

To subtract these two fractions, you need to have a common denominator. In this case, the common denominator is 64. To make 1/2 have a denominator of 64, you can multiply both the numerator and denominator by 32:

1/2 = (1 * 32)/(2 * 32) = 32/64

Now, subtract the fractions:

25/64 - 32/64 = (25 - 32)/64 = -7/64

So, the final result is:

(5/8) * (5/8) - 1/2 = -7/64
