The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

When multiplying/dividing measurements the answers needs to have the same amound significant figures as the one with the LEAST amount

Forget about "significant figures"; those are used to determine the precision when you multiply or divide. When adding numbers, the rule is that the result should be rounded according to the precision of the least accurate of the addents. In this case, to one decimal digit.

Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places

Yes, the precision of an answer depends on the precision of the measurements used in the calculation. The number of significant figures in the answer should match the least number of significant figures in the measurements.
