let's firstly convert the mixed fractions to improper fractions and then add, bearing in mind that the LCD from 8 and 4 is simply 8.
The answer would be 20.
How?
7 + 9 = 16
16 + 4 = 20
If you would like to know two equivalent ratios for 12/60, you can calculate this using the following steps:
12/60 = 12/2 / 60/2 = 6/30
6/30 = 6/2 / 30/2 = 3/15
3/15 = 3/3 / 15/3 = 1/5
The result would be 6/30 or 3/15 or 1/5.
