Agustin says that he can hold his breath for 90 seconds. and, he says that he did this 5 times this week. he used fractions and multiplication to calculate how many minutes he held his breath this week.

By multiplying 90 seconds to the 5 times he held his breath, you get 450 seconds. then to convert that to minutes, divide by 60... you get 7.5. which is 7 minutes and 30 seconds
