Each square below represents one whole.

a square divided in 4 equal parts, all 4 of which are shaded

another square divided in 4 equal parts, 3 of which are shaded

what percent is represented by the shaded area?

\%%

Percent means per hundred.

So, we need an equivalent ratio that will tell us how many pieces would be shaded out of 100 pieces per whole.

Ratio: is 7:4 because 7 are shaded and 4 because the two squares are divided into fours

4 times 25 is 100

so also Multiply 7 by 25  

7 x 25 is 175

175% is represented by the shaded area.

Here's a picture I made of what the squares should look like:

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

i got 10.28 but that rounds up to 10.3
