70/18 + 45/60 is 167/36.

1. Find the least common denominator or LCM of the two denominators:
LCM of 18 and 60 is 180
2. For the 1st fraction, since 18 × 10 = 180,
70/18 = 70 × 10/18 × 10 = 700/180
3. Likewise, for the 2nd fraction, since 60 × 3 = 180,
45/60 = 45 × 3/60 × 3 = 135/180
700/180 + 135/180 = 700 + 135/180 = 835/180
5. 835/180 simplified gives 167/36
