Answer:
75
Step-by-step explanation:
For this, you need to solve a proportion-
3.4 x
----- = -----
1.8 39.75
3.4*39.75=135.15
135.15/1.8= 75.0833.....
75.0833.. is rounded to 75
Check the picture below.
let's firstly convert the mixed fractions to improper fractions.

Answer:
85/100
Step-by-step explanation:
There are only 2 numbers after the decimal point which means that is 0/100. You would get 85/100 and you can't simplify more than that.
Hope This Helps :)
Your going to have to use the distance formula for these questions which is the square root of (x sub 2 - x sub 1) + (y sub 2 - y sub 1). For number 1 your coordinates are (-5,5) and (1,-2). Substituting these values into the formula your answer for number 1 is 9.2.
