The correct value according to Ruler A is 2.2 cm, whereas the correct value according to Ruler B is 2.27 cm. Perform the mathematical operations indicated by the title of each bin using these two values. Round the correct answers to the appropriate number of significant figures or decimal places. Compare the rounded correct answers with the values given and drag the rounded correct answers to the bin that represents the mathematical operation performed. There are also answers that are not rounded to the correct number of significant figures or decimal places. Drag these answers to the bin named "Incorrect rounding." For example, multiply the number 2.2 by 2.27. Round the answer to the appropriate number of significant figures. Drag the correctly rounded answer to the bin labeled "2.2 x 2.27." Drag the incorrect answers from the multiplication operation to the bin named "Incorrect rounding."

Please answer question 12 part B

Rules for rounding off answers in calculations While performing a mathematical operation on numbers that vary in significant figures, you follow certain rules. These rules are as follows: 1. For multiplication or division, the answer will have the same number of significant figures as that of the number that has the fewest significant figures. For example, when multiplying 1.2, 1.58, and 1.222, the product will be equal to 1.2 × 1.58 × 1.222 = 2.3169. However, this number will be rounded off to two significant figures because 1.2 has the fewest significant figures. Thus, the product will be 2.3. 2. For addition or subtraction, the answer will have the same number of decimal places as that of the number with the fewest decimal places. For example, when adding 1.2, 1.58, and 1.222, the sum will be equal to 1.2 + 1.58 +1.222 = 4.002. However, this number will be rounded off to 4.0, as 1.2 is the number with the fewest decimal places. Part B The correct value according to Ruler A is 2.2 cm, whereas the correct value according to Ruler B is 2.27 cm. Perform the mathematical operations indicated by the title of each bin using these two values. Round the correct answers to the appropriate number of significant figures or decimal places. Compare the rounded correct answers with the values given and drag the rounded correct answers to the bin that represents the mathematical operation performed. There are also answers that are not rounded to the correct number of significant figures or decimal places. Drag these answers to the bin named "Incorrect rounding." For example, multiply the number 2.2 by 2.27. Round the answer to the appropriate number of significant figures. Drag the correctly rounded answer to the bin labeled "2.2 x 2.27." Drag the incorrect answers from the multiplication operation to the bin named "Incorrect rounding."
