Explanation:
What we need to do is to convert
into a new - but still equal - fraction, one with a denominator of 3. In order to convert a fraction, you either divide or multiply both the denominator and the numerator by the same number.
We know that the answer has to be a fraction with the denominator of 3. Take a look at the denominator of
- it's 12. Ask yourself: 12 divided by what number equals 3? That number would 4.
So, divide 8 by 4 as well and you would get 2. Therefore, the numerator would be 2 and the answer is
.

Answer:
The number is 10
Step-by-step explanation:
Let the number be x.
four thirds times = 4/3
According to the statement:
four thrids times the sum of a number and 8 is 24
4/3 *(x+8)= 24
Move 3 to the R.H.S and Multiply 4 with the parenthesis.
4x+32=24*3
4x+32=72
Move constant to the R.H.S
4x=72-32
4x=40
Divide both the terms by 4
4x/4=40/4
x=10
Therefore the number is 10....
