Answer:
Decimal = 0.045 Fraction = 9/200
Explanation:
Decimal
To turn a percentage into a decimal, you need to divide by 100 OR move the decimal point two times to the right.
4.5 / 100 = 0.045
Fraction
Now for fractions it is different. Normally you would also divide by 100 and then put what you get over 100 but in this situation it is different. Here you would actually Multiply by 10 so that you decimal becomes a whole number.
4.5 x 10 = 45
Then, you take 100 and multiply it by whatever you multiplied you percentage with. This will be your denominator.
100 x 10 = 1000
Fraction = 45/1000
Now you need to simplify. Find the greatest common factor and divide it by that.
The GCF here is 5.
45/5 = 9
1000/5 = 200
Your final answer is 9/200
