(5/8)+(2/5)=
so you need a common den so in this case its 40
so we multiply to get 40 like
(5/5)(5/8)+ (2/5)(8/8)=
25/40 + 16/ 40 = 41/40
For example: 35 divided by 5 is 7. So to check with multiplication, just think 7 times 5 is what? 35. This is the same formula for everything.
Hope this helps!!
40+35.5 = 75.5
49.99 + 8.79 = 58.78
