Studdy Solution

STEP 1

Assumptions1. The numbers given are .505 and .. We are performing a division operation3. We need to apply Rule #, the multiplication and division rule for significant figures

STEP 2

First, let's perform the division operation.
Answer=.505/.2Answer = .505 / .2

STEP 3

Calculate the answer.
Answer=.505/.2=2.525Answer = .505 / .2 =2.525

STEP 4

Now, we apply Rule #2 for significant figures. In multiplication and division, the result should have the same number of significant figures as the number with the least significant figures in the operation.

STEP 5

Count the number of significant figures in each number.The number .505 has three significant figures (5,0,5) and the number .2 has one significant figure (2).

STEP 6

Since .2 has the least number of significant figures (1), our answer should also have one significant figure.

STEP 7

Round off the answer to one significant figure.The number2.525 rounded to one significant figure is3.
So, the answer to the problem is3.
