Amira is painting a rectangular banner 2 3/4 yards wide on a wall in the cafeteria. the banner will have a blue background . amira has enough blue paint to cover 1 1/2 square yards of wall.
find the length of the banner if amira uses all of the blue paint.

The length of the banner if Amira uses all of the blue paint is

Solution:

Given, Amira is painting a rectangular banner yards wide on a wall in the cafeteria.  

The banner will have a blue background

Amira has enough blue paint to cover square yards of wall.  

We have to find the length of the banner if Amira uses all of the blue paint.

Now we know that, area of rectangle = length x width  

Hence, the length of the rectangle is yards.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
