Answer:
Question 2. 12% of 650 = 78
Step-by-step explanation:
100% = 1 in decimal form.
This is because finding 100% of something is the same as multiplying it by 1:
E.g. 100% of 10=10, 10x1 = 10
Therefore to find a percentage of something, we simply need to multiply it by the decimal form of that percentage. For example, if we were finding 50% of 10 (half), 50% in decimal form is 0.5, 10x0.5 = 5
The percentage here is 12%, we can find the decimal form by dividing it by 100, 12/100 = 0.12
So, in order to find 12% of 650, we just need to multiply 650 by 0.12:
650x0.12 = 78
12% of 650 = 78
