To determine the number of significant figures in the result of a multiplication, you need to identify the number of significant figures in each of the numbers being multiplied.
1. The number 1.22 has 3 significant figures.
2. The number 0.91 has 2 significant figures.
When performing multiplication, the result should be reported with the same number of significant figures as the measurement with the least number of significant figures.
In this case, 0.91 has the least number of significant figures (2). Therefore, the result of \( 1.22 \times 0.91 \) should be reported with **2 significant figures**.
So the answer is **2**.
