When you convert 0.63 to a fraction which of the following could be the first step of the process

To convert a Decimal to a Fraction follow these steps: 
Step 1: Write down the decimal divided by 1. 
Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal, then use 100, if there are three then use 1000, etc.) 
Step 3: Simplify (or reduce) the fraction 

Example 1: Express 0.75 as a fraction 
Step 1: Write down: 
0.75 \1 

Step 2: Multiply both top and bottom by 100 (because there were 2 digits after the decimal place): 
× 100 

0.75 = 75 

1= 100 

(Do you see how it neatly turns the top number 
into a whole number?)
