A small ________________ holds 75% as much as a large _________________.

Leto [7]

Answer: The large ____ holds 48 units.

For the diagram you could draw the small rectangle 4 squares wide and 9 squares long. that will represent something that holds 36 units.

For the large one make it 4 squares wide and 12 squares long. That will have spaces for 48 units.

Step-by-step explanation: Change the percent to a decimal and set up the equation that means 36 is 75% of some number, yet unknown, X is the unknown number.

36 = .75x divide both sides by .75

36/.75 = .75x/.75 . The .75 "cancels" on the right. Then use a calculator.

36 ÷ .75 = 48

x = 48

Demi has 221 songs on her phone. The songs take up 884 megabytes of storage . Each song takes up same amount of space . How many

sveticcg [70]

Answer:

540 megabytes

Step-by-step explanation:

We will first need to find out how much space a singular song will take up. We will do this by the storage taken up (884) by the number of songs she has:

884 / 221 = 4 mb taken up per song

Then we want to find out how many megabytes 135 of these songs take up, so we will multiply the mb taken up per song (4) by the number of songs we want to find (135):

4 x 135 = 540 megabytes

Edit: made a mistake in my original answer, apologies!
