To determine the number of significant figures in the result of the multiplication [tex]\(1.22 \times 0.91\)[/tex], we need to look at the number of significant figures in each of the factors involved in the calculation.
1. The number [tex]\(1.22\)[/tex] has 3 significant figures. The digits 1, 2, and 2 are all significant.
2. The number [tex]\(0.91\)[/tex] has 2 significant figures. The digits 9 and 1 are significant, while the leading zero is not.
When multiplying numbers, the number of significant figures in the result is determined by the factor with the least number of significant figures. In this case, [tex]\(0.91\)[/tex] has the fewest significant figures, which is 2.
Therefore, the result of multiplying [tex]\(1.22\)[/tex] by [tex]\(0.91\)[/tex] should be reported with 2 significant figures.
The correct answer is:
2
