Question

How many seconds are there in 3/4 of a minute?

Answer 1

For this case the first thing you should know is the following conversion:
 $1 minute = 60 seconds$
 We can then make the following rule of three:
 1 minute ----------> 60 seconds
 3/4 minutes -------> x
 From here, we clear the value of x.
 We have then:
 $x = (3/4) * (60) x = 45 s$
 Answer:
 there are 45 senconds in 3/4 of a minute

Answer 2

45 seconds. Since there are 60 seconds in a minute and 60/4 is 15. 15*3 is 45. Hope this helped!
