what is the rate and unit rate of 21 meals in 7 days?

21/7 = 3

So the unit rate is 3 meals a day.

To find the rate, we need to determine the number of meals consumed in a given time period. In this case, we have 21 meals consumed in 7 days.

To find the rate, divide the number of meals by the number of days:
Rate = Number of meals / Number of days

Rate = 21 meals / 7 days

Simplifying the expression:
Rate = 3 meals per day

Therefore, the rate of 21 meals in 7 days is 3 meals per day.

To find the unit rate, we need to express the rate in terms of one unit. In this case, we want to find the number of meals consumed in one day.

To calculate the unit rate, simply divide the rate by the number of days:
Unit Rate = Rate / Number of days

Unit Rate = 3 meals / 1 day

Simplifying the expression:
Unit Rate = 3 meals per day

Therefore, the unit rate of 21 meals in 7 days is 3 meals per day.
