Final answer:
To convert 7/80 to a percentage, first divide 7 by 80 to get 0.0875, then multiply by 100 to get 8.75%, which is the unrounded percentage.
Step-by-step explanation:
To write 7/80 as a percentage, you first need to convert the fraction to a decimal. You do this by dividing the numerator by the denominator. So, you would calculate 7 ÷ 80 which equals 0.0875. After obtaining the decimal, you would then convert the decimal to a percent by multiplying it by 100 and adding a percentage sign. In this case, 0.0875 × 100 equals 8.75%. When rounding to the nearest tenth of a percent, the value of 8.75% remains the same since the hundredth place is a 5, and you would round up if it were greater than 5.
