Answer 1

To find differences in subtraction problems, subtract the smaller number from the larger one while aligning the decimal places. Pay attention to significant figures for precision, and round the answers to the appropriate decimal place or significant figure as required.

Step-by-step explanation:

To find the differences in the given mathematical problems, we need to subtract the smaller number from the larger number. For example:

• a. 58.7 - 29.7: To find this difference, you would subtract the tenths place of both numbers since they align, resulting in 58 - 29 at the tenths place and a difference of 29.0.
• b. 494 - 298: To find this difference, align the hundreds, tens, and ones place of both numbers and then subtract. Starting from the right, we subtract each digit, resulting in a difference of 196.

When reporting answers with significant figures, for example:

Remember to always pay attention to the significant figures and decimal places of the numbers you are working with to ensure your final answer is as accurate as possible.
