Explanation:</h2><h2 />
When we say "a is at most b" we mean that "a is less than or equal to b" or "a is not greater than b". So let's solve this problem as follows:
Step 1. Twice the difference of a number and 2
Let's call that unknown number as n. Then, twice the difference of a number and 2 is:

Step 2. Twice the difference of a number and 2 is at most -27

So the mathematical form of the statement <em>twice the difference of a number and 2 is at most -27 </em>is:

The answer is 3 3x3x3=9

180
This is because 12x5x3 = 180
1m= 1000mm
so 64mm*1m/1000mm=64/1000m
310 - 220 = 90
90/310 = x/100 (cross multiplication)
9000 = 310x
9000/310 = x
x = around 29%
