#2.9#

We have: #2 frac(7)(8)#

#= 2 + frac(7)(8)#

#= 2 + 0.875#

#= 2.875#

We need to approximate the number to one decimal place, so let's look at the digit of the second decimal place.

In this case, the digit is #7#, which is greater than #5#.

So we have to round up one decimal place:

#approx 2.9#
