In 2007, the fee to park in a parking garage was $40. In 2005 the fee was 3/4 of the fee in 2007. What was the fee in 2005? $10
Murljashka [212]

Answer:

C. $30

Step-by-step explanation:

So we know that in 2007 the fee was $40 and we want to figure out what is 3/4 of 40.

To solve that we can start off with 40 and divide it by 4. Which is like saying "I'm finding what one fourth of 40 is." The answer to that is 10.

Because 10 is ONE fourth we multiply by 3 to find what 3/4 of 40 is. 10x3=30 and that's why 3/4 of 40 is 30.

Hope that helps and have a great day!

Lyle bought 3/8 pound of red grapes and 5/12 of green grapes. How many pounds of grapes did he buy ?
STatiana [176]
He bought 19/24 pounds of grapes.
You need to find the common denominators then add.

3/8 = 9/24 - Red grapes
5/12 = 10/24 - Green grapes

10/24 + 9/24 = 19/24.
Therefore, he bought 19/24 pounds of grapes.
Hope this helped! :-)
