Tell what part of the circle is shaded​
DIA [1.3K]

Answer:

Fraction = 1/4, Decimal = 0.25, Percent = 25%

Step-by-step explanation:

Given the picture, we can see the circle is divided into four pieces. One of the pieces is shaded. So, since we have one out of four pieces shaded, we would represent this as 1/4 as a fraction. As a decimal, enter 1 divided by 4 into your calculator, and it will give you 0.25. To find a percentage value, take your decimal and multiply it by 100. 0.25*100= 25%
