Question

They want me to round the result to the correct number of significant figures.

Answer 1

The first part:

`24.9*1.99=49.551`

Since the first number is 1 decimal place and second number is 2 decimals, we will round to 1 decimal.

Thus,

49.551 = 49.6

Next part of the problem becomes:

`49.6/106.19`

The calculation provides the answer: 0.4670...

The first number has 3 significant figures, that's the limit because next number has 5 significant figures. So, we round off our answer to 3 significant figures (3 decimal place, in this case)

Thus, the answer is:

0.467
