I dont know how to do number 18 on my homework

Sagot :

Beth walked 3 blocks in 15 minutes.

Then, we have that:

[tex]\frac{3}{15}\cdot\frac{3}{3}=\frac{9}{45}[/tex]

We have that multiplying the rate (ratio) by the same number in the numerator and in the denominator, we will have equivalent fractions (and the same ratio).

Option a is true. We have the result above.

Then, for option b, we cannot obtain an equivalent fraction. It is false.

For option c, we have the same as for option b. It is false.

For option d:

[tex]\frac{3}{15}\cdot\frac{4}{4}=\frac{12}{60}[/tex]

Then, option d is true.
