Help with equivalent ratios?

See below.

Step-by-step explanation:

Problem 1:

All answers are correct.

Problem 2:

You have the ratio 240 to 1/5. You want an equivalent ratio of some number to 1. You need to change the second number from 1/5 to 1. For equivalent ratios, you can multiply or divide both numbers of the ratio by the same number. What multiplication can you do to 1/5 to end up with 1? Multiply 1/5 by 5 since 5 * 1/5 = 1. The multiplication you do to 1/5 to end up with 1 is "multiply by 5." Since you must do the same multiplication or division to both numbers of a ratio, you multiply both 240 and 1/5 by 5 to get an equivalent ratio.

Multiply by 5

Problem 3:

The ratio is 240 ft to 1/5 minute.

We saw in problem 2 that you must multiply both numbers by 5 to end up with 1 as the second number, so let's do those multiplications.

240 ft to 1/5 minute =

= 240 ft * 5 to 1/5 minute * 5

= 1200 ft to 1 minute

We see that the rate 240 ft to 1/5 minute is equivalent to the rate 1200 ft to 1 minute.
