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.
Answers
Answer:
15/2 or 7.5 minutes
Step-by-step explanation:
90 seconds is equal to 1.5 or 3/2 minutes.
Since he held the breath 5 times this week, in total he held his breath for 5*3/2 minutes.
= 7.5 or 15/2 minutes in total.
Answer:
Agustin held his breath for a total of 7.5 minutes this week (5 times for 1.5 minutes each time).
Step-by-step explanation:
If Agustin can hold his breath for 90 seconds, then he can hold his breath for 1.5 minutes (since there are 60 seconds in a minute). To calculate how many minutes, he held his breath this week, we need to multiply the number of minutes he held his breath each time by the number of times he did it.
Since Agustin did this 5 times this week, we can represent this as a fraction: 5/1. To multiply this fraction by the number of minutes he held his breath each time (1.5), we multiply the numerator by 1.5:
5/1 x 1.5 = 7.5
Therefore, Agustin held his breath for a total of 7.5 minutes this week (5 times for 1.5 minutes each time). By using fractions and multiplication, we can easily calculate how long Agustin held his breath in total without having to add up 90-second intervals five times.
