Final answer:
b. 1.0. To divide the fraction, divide the numerator by the denominator and round the answer to the nearest tenth.
Step-by-step explanation:
To divide the fraction, we simply divide the numerator by the denominator. So, the division would be:
12.2 / 1.7 = 7.2
Since we need to express the answer to the nearest tenth, we round the decimal to one decimal place. When rounding, if the digit after the decimal point is 5 or greater, we round up. If it is less than 5, we round down.
In this case, the digit in the tenths place is 2, which is less than 5. Therefore, the nearest tenth is 7.0.
So, the correct answer is 7.0 (option b).
