Graph the following number on the number line below 16/4, -2.7, 1.75, 1/5

Assuming that you need to place the numbers on a number line; 

1) Convert all numbers in one form, be it fraction or decimals

16/4 = 4 
-2.7 = -2.7 
1.75 = 1.75 
1/5 = 0.2 

2) Draw a number line with zero in the middle and positive numbers going to the right. The negative numbers go on left. 

3) Place the decimal/fraction numbers into the number line, using a constant interval. 

Hope I helped :)
