Answer: 5/24
Explanation: To subtract unlike fractions such as 7/8 - 2/3, first find a common denominator. The common denominator of 8 and 3 will be the least common multiple of 8 and 3 which is 24.
To get a 24 in the denominator of 7/8, we multiply both the numerator and the denominator by 3 to get 21/24.
To get a 24 in the denominator of 2/3, we multiply both the numerator and the deliminator by 8 and to get 16/24.
Now we are subtracting like fractions since both fractions have the same denominator or bottom number of 16.
To subtract like fractions, we simply subtract the numerators and keep the same denominator. So here, we have 21/24 - 16/24 which is 5/24.
Since 5/24 is in lowest terms, it's our final answer.
This means that 7/8 - 2/3 is 5/24.
