Question

What is 5 1/6 minus 1 1/3

Answer 1

We must find the common denominator.

LCM(6, 3) = 6

`5(1)/(6)-1(1)/(3)=5(1)/(6)-1(1\cdot2)/(3\cdot2)=5(1)/(6)-1(2)/(6)=(5-1)+\left((1)/(6)-(2)/(6)\right)=4-(1)/(6)=3(5)/(6)`

or other method of calculating the difference

`5(1)/(6)-1(2)/(6)=4(6+1)/(6)-1(2)/(6)=4(7)/(6)-1(2)/(6)=(4-1)+\left((7)/(6)-(2)/(6)\right)=3(5)/(6)`
