Answer:
a. 12%
b. 0.12
Explanation:
To make it easier to write it in both forms, you can make it into a fraction with 100 in the denominator.
You know that 25 * 4 = 100, so you would want to multiply both the numerator and the denominator by 4.
(3*4)/(25*4) = 12/100
12/100 is equal to 12%.
You can move the decimal two places to the left to divide it by 100.
12/100 is also equal to 0.12.
