A unit rate is a rate that has been reduced to have a denominator of 1 unit.

34 grams of fat per tablespoon of powder.

Practice makes perfect
A unit rate is a rate that has been reduced to have a denominator of 1 unit. We know that there is 14 gram of fat for every 13 tablespoon of powder. We want to find how many grams of fat are for every 1 tablespoon of powder — the unit rate. Let's write a ratio to show that here is 14 gram of fat for every 13 tablespoon of powder. 14grams/13tablespoon or 14/13 To find the unit rate, we write an equivalent rate with a denominator of 1.
14/13
1/4 * 3/1
3/4
34/1
The unit rate is 34 grams of fat for every tablespoon of powder.
