Given:
7.4521
Round to 2 significant figures.
Solution:
In rounding numbers, it must be taken to note that if the number is greater than or equal to 5 then the succeeding number will be added by 1, hence if the number is less than 5, then the succeeding number will remain the same. Since we are asked to round to 2 significant figures, then we will round in the tenths place. 4 is located in the tenths place and before 4, we have the value of 5, which is equal to 5, therefore, we will add 1 to 4.
= 7.5
Final answer
= 7.5
