#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
