6-3/4x+1/3=1/2x+5 what number can be used to get rid of all fractions
Yanka [14]

The number can be used to get rid of all fractions is 12

<h3>What number can be used to get rid of all fractions?</h3>

The equation is given as:

6 - 3/4x + 1/3 = 1/2x + 5

The denominator of the fractions are:

4, 3 and 2

The LCM of 4, 3 and 2 is 12

So, we have:

12 * [6 - 3/4x + 1/3] = 12 * [1/2x + 5]

Evaluate the products

72 - 9x + 12 = 6x + 60

Hence, the number can be used to get rid of all fractions is 12
