A number that is increased by 50% and then decreased by 50% is called sequential percentage calculation or successive percentage calculation.

50 percent minus 50 percent is 0 percent, but you cannot simply take 0 percent of a number to get the correct answer when you want to increase a number by 50 percent and then decrease the result by 50 percent.

rjkz [21]

Answer:

10.3125 (NOT  ROUNDED)

Step-by-step explanation:

1. I changed it to decimals. 1/4 can easily be changed into a decimal.

2. I set 1/4 = x/100. Then cross multiplied. That would give you 4x = 100.

3. Now you would simplify that. x would be 25. So its 25/100 wich then turns to .25.

4. Now you are going to replace them so it would be 1.25 and 8.25.

5. To find out how much milk chocolate there was you would multiply 1.25 and 8.25.

6. That's your final answer

the best way to solve any of theses is in the order of pemdas:

●parentheses

●exponents

●multiplication & division

●addition & subtraction

for example lets do #2

9+ (2^2)(4)

the first parenthesis has exponents so you'd do it first. 2^2 (two two times) is 4

9+(4)(4)

when two parentheses are next to Each other you multiply. 4x4 is 16

9+16
