Answer: 1/2
Explanation: To subtract unlike fractions such as 4/5 - 3/10, first find a common denominator.
The common denominator of 5 and 10 is the
least common multiple of 5 and 10 which is 10.
To get a 10 in the denominator of 4/5, we multiply both the numerator and the denominator of 4/5 by 2 to get the equivalent fraction 8/10.
Notice that 3/10 already has a 10 in the
denominator so it stays the same.
So we have 8/10 - 3/10 which is 5/10.
5/10 can be simplified to 1/2.
