Question #a02ea

Answer 1

`4.75 xx5=20`
`1.99/3=0.7`

Explanation:

`4.75 xx5=23.75` this should be corrected to one significant figure, then it is rounded to `20`, because 5 is one significant figure.

`1.99/3=0.66` this should also be corrected to one significant figure, then it is rounded to `0.7`, because 3 is one significant figure.
