Explanation:
100% = 12 throws
what are 150% ?
so, the question really is, what do I need to multiply 100(%) with to get 150(%) ?
100×x = 150
x = 150/100 = 1.5
so, since 100% and 12 throws are equivalent, we need to multiply the number of throws with the same factor x :
12×1.5 = 18
so,
150% = 18 throws.
she made 18 throws.
