Question

Use a model to divide. Express the answer in simplest terms. If necessary, use / for the fraction bar.

A) 5 1/2
B) 5 3/4
C) 5 1/4
D) 5 2/3

Answer 1

To divide a whole number by a fraction, we can multiply the whole number by the reciprocal of the fraction. In this case, we can multiply 5 by the reciprocal of 1/4, which is 4/1. The result is 20/1 or simply 20.

The correct option is C.

Step-by-step explanation:

To solve this problem, we can use a model to divide the given fractions. Let's take one of the options, for example, option C) 5 1/4. We can divide 5 by 1/4 by multiplying 5 by the reciprocal of 1/4. The reciprocal of 1/4 is 4/1. So, 5 divided by 1/4 can be written as 5 * 4/1. When we multiply the numerators (5 * 4), we get 20. And when we multiply the denominators (1 * 1), we get 1. Therefore, the answer to 5 divided by 1/4 is 20/1 or simply 20.
