Sarah and her friends ordered a pizza. Sarah ate 5 1 of the pizza. Her friend John ate 20% and her friend Jules ate half of the pizza. How much pizza is left over?

Given:

Sarah ate of the pizza.

Her friend John ate 20%.

Her friend Jules ate half of the pizza.

To find:

The remaining part of the pizza.

Solution:

We have,

Sarah ate = of the pizza.

John ate =  of the pizza.

              =  of the pizza.

              = of the pizza.

Jules ate = of the pizza.

Total part of a pizza they ate =

                                 =

                                 = of the pizza.

Now, the remaining pizza is

Remaining pizza = 1 - Total part of a pizza they ate

                            = of the pizza.

                            = of the pizza.

                            = of the pizza.

Therefore, the remaining pizza is of the pizza.                        

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
