I don’t get number 7

Answer:
Correct answer is C 0.86
Step-by-step explanation:
The best way to do this kind of problem with decimals is to make it into a problem that is close to 100.
[tex]\frac{43}{50}[/tex], but that may be difficult without a calculator to find the decimal of 43/50.
If you multiply 43/50 by 2, you would get [tex]\frac{86}{100}[/tex] which can also be written as [tex]0.86[/tex]
