Hi there!
The first thing we need to do is take this 1 1/2 hours in put it in decimal. It will make it more easy to solve. So let's do it :)
= 1.5 hours
So, the problem says that Shane downloaded 7 songs in 3 minutes. And they want us to find how many songs she can download in 1.5 hours.
We know there are 90 minutes in 1 1/2 hours.
So we gonna say:
If Shane downloaded 7 songs in 3. How many songs she can download in 1 1/2 hours.
It looks like this
7 songs .......> 3mn
x songs ..........90mn
Cross multiply
3x = 90 * 7
3x = 630
x = 630/3
x= 210
We got it!
Shane can download 210 songs in 1 1/2 hours.
Good luck with your studies!
