Question #45f8c

Answer 1

`6.79`

Explanation:

Find the upper and lower bounds of `a and b` first.

`a` has been rounded to `2` decimal places:

`0.01 div 2 = 0.005`

`2.295 < a < 2.305`

`b` has been rounded to `1`decimal place :

`0.1 div= 0.05`

`15.65 < b < 15.75`

To find the lower bound for a division means you want the smallest possible answer.
This will come from : #("lower bound for " b)/("upper bound for " a)#

`15.65/2.305`

`=6.78957.. rarr 6.79` to 3 sf
