Answer:
The least common denominator of the fractions is 24
Step-by-step explanation:
we know that
The <u>least common denominator</u> (LCD) is the smallest number that can be a common denominator for a set of fractions
so
we have
7/8
Multiples of 8 -------> 8,16,24,32,...
5/6
Multiples of 6 -------> 6,12,18,24,...
24 is a common multiple of 6 and 8. It is their lowest common multiple
<em>Alternative Method</em>
we have
![8=2^{3}](https://tex.z-dn.net/?f=8%3D2%5E%7B3%7D)
![6=2*3](https://tex.z-dn.net/?f=6%3D2%2A3)
The least common multiple are those common and non-common numbers with the greatest exponent
so
![lcm= 2^{3}*3=24](https://tex.z-dn.net/?f=lcm%3D%202%5E%7B3%7D%2A3%3D24)
