Nathan does push ups for the same amount everyday. he does 9 minutes of push ups for 3 days. how many minutes of push ups does nathan do in 7 days?

21 minutes

work: okay, so to solve this we need to find the unit rate, or number of minutes he spends doing pushups each day, to be ale to see how many he does in 7 days.

so, to find the unit rate, divide the number of minutes by days.

9/3 = 3

so, this means he spends 3 minutes a day on pushups.

to find out how many he completes in 7 days, multiply how many minutes he spends a day (3) by the number of days (7)

3 x 7 = 21

so, he spends 21 minutes doing pushups in 7 days.
