Answer:
Step-by-step explanation:
To round 0.42 to the nearest tenth of a percentage, we first need to convert it to a percentage. We can do this by multiplying it by 100:
0.42 * 100 = 42
So 0.42 is equivalent to 42%. To round 42% to the nearest tenth, we need to look at the digit in the hundredths place, which is 2. Since 2 is less than 5, we round down to the nearest tenth. Therefore, 42% rounded to the nearest tenth is 40%
