7/8-1/4=

1 answer

To subtract fractions, we need to have a common denominator. The common denominator for 8 and 4 is 8*4 = 32.

So, we rewrite the expression as:
7/8 - 1/4 = (7/8)*(4/4) - (1/4)*(8/8)

Multiplying the numerators and denominators, we have:
= 28/32 - 8/32

Now, we can subtract the fractions:
= (28 - 8)/32
= 20/32

The fraction 20/32 can be simplified by dividing the numerator and denominator by their greatest common factor, which is 4:
= 5/8

Therefore, 7/8 - 1/4 = 5/8.
