The problem here is to subtract 1/1 and 3/8
These two fractions do not have the same denominators (lower numbers), so we must first find a common denominator of the two fractions, before subtracting them.
For the denominators here, the 1 and 8, a common denominator for both is 8.
With the common denominator, the 1/1 becomes a 8/8
and the 3/8 becomes a 3/8
So now our subtraction problem becomes this...
The problem here is to subtract 8/8 and 3/8
Since these two fractions have the same denominators (the numbers under the fraction bar), we can subtract them by simply subtracting the numerators (the 8 - 3 = 5), while keeping the same denominator (the 8).
Our answer is 5/8
