8/2.5 + 3/1 = 8/2.5 + 15/2
Finding a common denominator of 5, we convert both fractions:
8/2.5 = 8 × 2 / 2.5 × 2 = 16/5 = 3.2
15/2 = 15 × 2.5 / 2 = 37.5 / 2 = 18.75
Now adding these gives 3.Still, 2 + 18. 75 = 21.Consider this: 95, which is approximately 22. This example illustrates how improper fractions can be manipulated and added effectively Simple, but easy to overlook..
