Lucy spends 4 hours a week babysitting.Her Sister Lily spends 7/8 as much time babysitting. Does Lily babysit for more or less than 4 hours?

7/8•4= 20/32
But then how do I break that down ?

So we divide 4 divide 7/8 ? Sorry

But is it more or less than 4 hours?

(7/8) * 4 = 28/8 = 3 4/8 = 3 1/2

Thank you so much Ms. Sue

Thank you so much. I need this for my homework.

I believe it is because 3 1/2 is less than 4

7/8•4 does not equal 20/32

To break down the fraction 20/32, you can simplify it by finding the greatest common divisor (GCD) of both the numerator (20) and the denominator (32) and then dividing both by the GCD.

The GCD of 20 and 32 is 4. So, divide both 20 and 32 by 4:

20 ÷ 4 = 5
32 ÷ 4 = 8

Now you have the simplified fraction, which is 5/8.

Therefore, Lily babysits for 5/8 of the time Lucy does. To compare this to 4 hours, you need to convert 5/8 into hours.

Let's assume that 4 hours is the total time Lucy spends babysitting in a week. To find out how much time 5/8 represents in hours, multiply 5/8 by 4:

(5/8) * 4 = (5 * 4) / 8 = 20/8

To further simplify the fraction, you can divide both the numerator and denominator by 4:

20 ÷ 4 = 5
8 ÷ 4 = 2

So, Lily babysits for 5/2 hours, which is equivalent to 2 hours and 30 minutes.

Therefore, Lily babysits for less time than Lucy, who babysits for 4 hours.

You're very welcome, Becca.
