Answer:
- Marsha's shading: 0.80
- Grace's shading: 2.40
Explanation:
You are being asked for the decimal equivalents of 0, 4/5, and 2 2/5.
You have correctly noted that the decimal equivalent of 0 is 0, or 0.0.
__
The decimal equivalents you want are apparently in hundredths. To find the fractional part, solve the proportion ...
(your fraction) = x/100 ⇒ x = 100×(your fraction)
So, for the decimal equivalent of 4/5, you have ...
x = 100(4/5) = 80
and the decimal is
80/100 = 0.80 . . . decimal representing Marsha's shading
__
Similarly, the decimal equivalent of 2/5 is ...
x = 100(2/5) = 40
2 2/5 = 2 40/100 = 2.40 . . . decimal equivalent of Grace's shading
