Question

Divide. Round your answer to the nearest tenth. 0.985-:0.31

Answer 1

To find 0.985 divided by 0.31, multiply both numbers by 100 to make the divisor a whole number and then perform the division to get 3.1774, which when rounded to the nearest tenth is 3.2.

Step-by-step explanation:

The question is asking to divide two decimal numbers: 0.985 by 0.31. To perform this division, we follow the standard procedure for dividing decimals:

1. Place the decimals above one another, aligning the decimal points.
2. If the divisor (0.31) is not a whole number, multiply both the divisor and dividend by a power of 10 to make the divisor a whole number. In this case, we multiply both by 100 to get 98.5 divided by 31.
3. Perform the division as you would with whole numbers.
4. Place the decimal point in the quotient (result) directly above where it appears in the dividend (98.5).

Now we can divide 98.5 by 31 to get approximately 3.1774.

After the division, we need to round the answer to the nearest tenth. The digit in the hundredths place is 7, so we round up. The final answer, rounded to the nearest tenth, is 3.2.
