Question

express number 3.612 and 29.87 correct to 2 significint

Answer 1

Answer:

3.6 and 30

Step-by-step explanation:

for 3.612,

the third significant figure is 1, i.e., <5,

so according to the rules, it becomes 3.6.

for 29.87,

the third significant is 8,i.e, >5 and so we need to add 1 to its right side if the number on the right is odd or no need to add if the number is even,

so here with the number 9 being odd, we add 1 to it, which gives us 30.
