It takes Marty 1 1/4 hours to get ready for school. If 1/5 of that time is used to shower, what fraction of an hour does it take him to shower?
1/4answer
1/4 because 4x1+1=5/4
5/4x1/5=(5x1) and (4x5)=5/20 divided by 5=1/4
I dunno!!!!!somebody plz answer this.
To find out what fraction of an hour it takes for Marty to shower, we need to determine how much time 1/5 of 1 1/4 hours represents.
First, let's convert 1 1/4 hours to an improper fraction:
1 1/4 = (4 * 1 + 1) / 4 = 5/4
Next, we find 1/5 of 5/4 hours by multiplying the numerator (5) by 1 and the denominator (4) by 5:
(5/4) * (1/5) = (5 * 1) / (4 * 5) = 5/20
Now, we simplify 5/20 by dividing both the numerator and denominator by their greatest common divisor, which is 5:
5/20 = (5/5) / (20/5) = 1/4
Therefore, 1/4 of an hour is equal to 1/5 of Marty's time taken to get ready for school. So, it takes him 1/4 of an hour, or 15 minutes, to shower.
1) first draw a diagram
2)aadd 1/4 5 times which gives u 1 1/4 so it is right
3)THERE IS UR ANSWER
it take Marty 1 1/4 hour to get ready for school .If 1/5 is used to shower. What fraction of an hour does it take him to shower?
1 1/4 = 1 + 1 / 4 = 4 / 4 + 1 / 4 = 5 / 4
5 / 4 * 1 / 5 = 5 / 4 * 5 = 1 / 4
