The correct value according to ruler a is 2.2cm, 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."
drag the appropriate items to their respective bins.
