Final answer:
The result of dividing 9.23 by 0.48, rounded to the nearest tenth, is 19.2. This corresponds to option a from the given choices.
Step-by-step explanation:
To calculate the result when 9.23 is divided by 0.48, and to round it to the nearest tenth, we perform the division:
9.23 ÷ 0.48 = 19.229166...
When rounding this to the nearest tenth, we look at the number in the hundredths place. Since it is a 2, which is lower than 5, we round down. Therefore, the final result rounded to the nearest tenth is 19.2.
Among the options provided, we have two instances of 19.2 (a and d). Assuming this is a typo in the options and considering the context, we select 19.2 as the rounded answer. Hence, the correct rounded answer is 19.2, which corresponds with option a.
