Hi
3/10 are shaded.
If one fifth of a region is not shaded then 4 fifths of the region is shaded. Fifths means there are five parts.
Well, darling, if you shaded all but three eighths of the rectangle, then the shaded area is 5/8 of the total rectangle. To find the percentage of the rectangle that is not shaded, you subtract the shaded area from 100%. So, 100% - 62.5% (5/8 as a percentage) = 37.5%. Voilà, 37.5% of the rectangle is not shaded.
35%
There are no circles to choose from!
Hi
If 5.7 of a region is shaded, then 94.3% of the region is not shaded. This can be calculated by subtracting the shaded percentage from 100%.

To find the area of the shaded part in a rectangle, you first find the total area of the rectangle by multiplying its length by its width. Then, you subtract the area of the non-shaded part from the total area to get the area of the shaded part. The formula would be: Area of shaded part = Total area of rectangle - Area of non-shaded part
78.75% is not shaded.
What do you call shaded part?
The shaded parts
Paula created a monthly budget. A pie graph shows a clear picture of where her money is spent. How much of the circle would be shaded for the total of housing, utilities, food, and insurance?

I presume that it means you have a choice of several charts and one of them may have 3 prime numbers that are shaded. There may be more than one such chart to make your task easier or they may not be any and it is a trick question!
