You have to make them have the same denominator so
1/2=2/4
Then you add them together
2/4+3/4=5/4
You have to make it a mixed fraction.
4 goes into 5 one time and has a remainder of 1 so you get 1 and 1/4?
D. 147 i hope it’s right if not i’m so sorry!
J = m - 1 1/4 (ft).......j = m - 15 inches...because 1 1/4 ft = 15 inches
m = L + 1/3 (ft).......m = L + 4 inches....because 1/3 ft = 4 inches
L = 62 inches
m = L + 4
m = 62 + 4
m = 66 inches or 5.5 ft <==Maria
j = m - 15
j = 66 - 15
j = 51 inches or 4.25 ft <== Juan
