Question

Hello, I need the help with understanding how to solve it. Thanks

Answer 1

Step 1:

In this question, we are given the following:

Step 2:

From the question, we need to find the least common denominator of 4 and 8.

First, what is the least common denominator?

The least common denominator is the smallest number of all the common multiples of the denominators when 2 or more fractions are given. Let's add two fractions.

The first common smallest multiple will be the least common denominator for the given fractions.

From the definition, we can now see that:'

The least common denominator (LCD) of:

`(9)/(4)\text{ and }(3)/(8)`

are:

Multiples of 4 are: 4, 8, 12, 16, ......

Multiples of 8 are: 8, 16, 24,....

Now, from the definition of Least Common Denominator, we can see that:

`\text{Least Co}mmon\text{ Denominator =8}`
