Question

A package of decorations holds 20 glow sticks for every 28 stickers. The ratio of

glow sticks to stickers is 20:28. Use division to find an equivalent ratio for 20:28, and
express it using words, using a colon, and as a fraction. Explain how you found the
equivalent ratio.

Answer 1

Answer: 5:7 and 10:14 are equivalents to 20:28

Explanation:

We have the ration 20:28, and we want to find equivalent ratios to this:

One way to do this is by dividing both numbers by the same number.

For example, both 20 and 28 are even numbers, then we can divide them by 2.

20/2 = 10

28/2 = 14.

Then we have that 10:14 is equivalent to 20:28.

And we can do it again, this time only with words:

10:14 means that for each 10 glow sticks, we have 14 stickers.

The taking half of each, we have that for each 10 = 5 + 5 glow sticks, we have 14 = 7 + 7 stickers.

Then the ratio 5:7 is also equivalent to 10:14 and to 20:28
