Answer:
The correct answer is a grid model with 25 squares where 10 squares are shaded.
Step-by-step explanation:
To solve this problem, we should convert each of the scenarios presented into fractions. To do this, we can use the following formula: (squares shaded/total number of squares). This gives us the following fractions:
10/25, 8/25, 10/40, 14/40
We are looking for a fraction that is equivalent to 40%. We should convert this percentage to a decimal by dividing by 100, which gives us 40/100 = 0.4. This means that we are looking for a decimal value of 0.4. To convert the fractions we have to decimals, we must divide each numerator by the denominator. If we do this, we get:
10/25 = 0.4
8/25 = 0.32
10/40 = 0.25
14/40 = 0.35
The 10/25 scenario is the only one that is equivalent to 0.4 (or 40%), thus this is the correct answer.
Hope this helps!
