Answer: You can multiply the numerator and the denominator by 2.
Step-by-step explanation:
Equivalent fractions are those fractions that represent the same number.
To find an equivalent fraction of a determined fraction, you need to multiply the numerator and the denominator by the same number.
Knowing the fraction , where the numerator is 1 and the denominator is 4, you can multiply each one (the numerator and the denominator) by 2 to obtain an equivalent fraction.
Then:

1st option
Step-by-step explanation:
the area of the shaded portion is calculated as
area of sector - area of white Δ
area of sector = area of circle × fraction of circle
= πr² × ( r is the radius )
= π × 8² ×
= 64π ×
= 16π in²
area of Δ = bh ( b is the base and h the perpendicular height )
here b = h = 8
area of Δ = × 8 × 8 =
× 64 = 32 in²
then
area of shaded portion = (16π - 32 ) in²
