How to do 3 4/5 ÷ 1 1/3
andrew11 [14]

Answer: 2 7/15

Step-by-step explanation: First, you make sure you have the same denominator on both of the fractions.

4/5 turns to 12/15 and 1/3 turns to 5/15

After that, then you do 12/15 - 5/15, which is 7/15.

Now you do 3 - 1.

Your answer should be 2 7/15.

I hope this helps you and I hope you have a blessed day!

The area of a circular plate is 625pi sqaure in. If the radius of the plate is tripled what is the new area
goldenfox [79]

Answer:

5625in²

Step-by-step explanation:

Area of the plate = πr²

625π = πr²

625 = r²

r = √625

r = 25in

If the radius of the plate is tripled, then the new radius will be 3(25) = 75in

New Area = π(75)²

New Area = 5625π in²

If the radius is tripled, the new area of the plate is 5625in²
