Alice is correct. If she multiplies the dividend and divisor by 4, the divisor becomes 1.
That one is true because if you multiply the divisor by 4, it becomes 0.25*4 = 1. Of course, you can't multiply the divisor without multiplying the dividend.
So 15.5 / 0.25 = (15.5 * 4) / (0.25 * 4) = 62 / 1
And we know that if you divide a number by 1, the answer is that number.
so 62/1 = 62.
Which means that Alice found the quotient without even dividing based on Answer C.
