1. B (15/8)
2. D (19/12)
3. A (5/2)
This one is pretty simple. The explanation is that to convert a mixed fraction into an improper fraction, you have to multiply the whole number by the denominator. After you have done that, you have to add the total of the product of the whole number and denominator, you add that by the numerator. And that’s it, pretty simple.
1.
8 x 1 = 8 + 7 = 15
15/8
2.
12 x 1 = 12 + 7 = 19
19/12
3.
2 x 2 = 4 + 1 = 5
