Which number can each term of the equation be multiplied by to eliminate the fractions before solving?
1 answer:
To eliminate the fraction, we multiply by 4
<h3>How to eliminate the fractions?</h3>The equation is given as:
-3/4m-1/2=2+1/4m
Rewrite properly as:
The denominators of the above fractions are 2 and 4
The LCM of 2 and 4 is 4
So, we multiply through by 4.
This gives
-3m - 2 = 8 + m
Hence, to eliminate the fraction, we multiply by 4
