4/5 + 16/20
= 4 x 4/ 5 x 4 + 16 x 1/20 x 1
= 16/20 + 16/20
= 32/20
= 16/10
= 8/5
= 1.6

4/5 + 16/20 = x
But 16/20 = 4/5 (divide both numerator and denominator by 4)
therefore
4/5 + 4/5 = x (4 apples plus 4 apples = 8 apples)
x = 8/5 or 1 and 3/5

4/5 is same as 16/20 (multiply top and bottom by 4)
Now 16/20 + 16/20
= 32/20 (Add Only the top part but not the bottom part)
= 8/5 (Divide top and bottom by 4)

you just add them like usual:
4+16 = 20
5+ 20 =25
this gives you 20/25 (which silmplified to 4/5)
You must add this to your original value (4/5)
4+4 = 8
This gives you an answer of 8/5
