Question

What is 1/7 of 28.....​

Answer 1

Answer:

4

Step-by-step explanation:

We need to perform a multiplication.

The following rule is applied:

A/B C = AC/B

In our example, the factors in the new numerator are:

28, 1,

Notice that all non-fraction factors are placed in the numerator.

The only factor in the new denominator is:

7

We need to reduce this fraction to the lowest terms.

This can be done by dividing out those factors that appear both in the numerator and in the denominator.

In our example, this is the common factor:

7

We need to evaluate a power by multiplying the base by itself as many times as the exponent indicates.

In our example, base 2 will be multiplied by itself twice.

Then we're left with our answer: 4
