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

Check

-3/4(-5/2) -1/2 = 2 + 1/4(-5/2)

15/8 -4/8 = 16/8 -5/8

11/8 = 11/8 . . . . . answer checks OK

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
