Final answer:
For the expression 17x430/120, the calculator value must be rounded to the ones position, giving a final rounded answer of 61.
Step-by-step explanation:
When evaluating the expression 17x430/120, it's important to use the correct order of operations and to understand significant figures. Using a calculator, you can perform the multiplication first (17 times 430) and then divide the result by 120. However, when it comes to rounding, we consider the significant figures in the original numbers. In this case, we are limited to the ones position because that is the farthest-right significant figure in both 430 and 120.
The calculator provides a raw answer, but it must be rounded appropriately. If the digit to the right of the ones position is 5 or higher, we round up. Thus, if your calculator gives you 60.916, you would round up to 61 to stay within the correct number of significant figures.
