Explain how to find 27% of 16 using multiplication by a decimal. Then explain how to use estimation to check your answer. Intro

the answer is 4.32

Step-by-step explanation:

-Obviously 16 is our 100% because its the output value of the task.

-Let's say x is what we are looking for

- if 16 is 100% and x is 27% write down 16=100% and x=27%

-now that we have that..where left sides of both of them have the same units, and both of the right sides have the same units, we do something like this 16/x=+100%/27%

- last just solve the simple equation

16/x= 100/27

(16/x)*x=(100/27)*x

16= 3.7037037037*x to get x

16/3.7037037037=x

4.32=x or x=4.32

-now we have

27% of 16=4.32

Convert 27% to the equivalent decimal 0.27. Multiply 16 by 0.27 to get 4.32. Use estimation to check the answer by choosing the friendly percent 25%. 25% of 16 is equal to 16 ÷ 4 = 4. The answer is reasonable.

Step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
