Question

The square below represents one whole. Express the shaded area as a fraction, a decimal, and a percent of the whole. Fraction: Decimal: Percent: %​

Answer 1

Fraction =

Decimal = 0.38

Percent = 38%

Explanation:

Number of shaded rectangles = 38

Total number of rectangles = 100

Fraction represented by the shaded area =

=

=

=

The decimal form of the shaded area = = 0.38

Percent of the shaded area = = 38%

Answer 2

Fraction =
`(19)/(50)`

Decimal = 0.38

Percent = 38%

Explanation:

Number of shaded rectangles = 38

Total number of rectangles = 100

Fraction represented by the shaded area =
`\frac{\text{Number of blocks shaded}}{\text{Total number of blocks}}`

=
`(38)/(100)`

=
`(19* 2)/(50* 2)`

=
`(19)/(50)`

Decimal form of the shaded area =
`(38)/(100)` = 0.38

Percent of the shaded area =
`(38)/(100)` = 38%
