Which number can each term of the equation be multiplied by to eliminate the fractions before solving? -3/4m-1/2=2+1/4m

4

Step-by-step explanation:

The fractions involved are 3/4, 1/2, 1/4. These have a least common denominator of 4. All of the fractions can be eliminated by multiplying the equation by 4.

-3/4m -1/2 = 2 +1/4m . . . . . . given

-3m -2 = 8 + m . . . . . . . . . . . multiply by 4 (eliminates fractions)

-10 = 4m . . . . . . . . . . . . . . . . add 3m-8

-5/2 = m . . . . . . . . . . . . . . . . divide by 4
