Answer:

m = 11 3/8

Step-by-step explanation:

50 - 19 3/4 - 18 7/8 = m

take 19 and multiply it by 4 then add 3, which will give you 79/4

then, take 18 and multiply it by 8 and add 7, which will give you 151/8

50 - 79/4 - 151/8 = m

m = 50 - 79/4 - 151/8

m = 50/1 - 79/4 - 151/8

find the least common multiple (LCM) of 1 and 4, which is 8

m = 400/8 - 158/8 - 151/8

m = 91/8

divide 91 \div 8, which equals 11

instead of putting remainder (r), you make it a mixed fraction

m = 11 3/8

Hope this helps!
