Hello from MrBillDoesMath!
Answer:
16
Discussion:
A common denominator is 16 as 7/8 can be converted to 14/16
Thank you,
MrB
For this case we have:
Form 1:
To obtain the common denominator, we must first obtain the minimum common multiple of both denominators, that is, if we have:
[tex]\frac {7} {8}\ and\ \frac {4} {16}[/tex]
We must obtain the minimum common multiple of 8 and 16, then:
[tex]8 = 2 * 2 * 2 = 2 ^ 3\\16 = 2 * 2 * 2 * 2 = 2 ^ 4 = 2 ^ 3 * 2[/tex]
So, the minimum common multiple is[tex]2 ^ 3 = 8[/tex]
Form 2:
You can also rewrite the first fraction as follows:
Multiplying the numerator and denominator by 2 we have:
[tex]\frac {14} {16}[/tex]
Therefore, the common denominator of both fractions is 16.
Answer:
Form 1: 8
Form 2: 16
Both answers are equivalent depending on what is required in the problem
