The answer is 37.5% because to change a decimal to a percent, you move the decimal over 2 places to the right, and since the decimal is behind zero, it ends up between 7 and 5.

Answer:

37.5%


Step-by-step explanation:


The question asks for "the percent of 9-year olds who prefer Superhero A"

[Note: Since the table is given in terms of decimal, we will do the problem in decimal and later change to percentage]

  • How many total 9-year olds are there?

Add the 9-year olds row. We have:

\(0.375+0.625=1\)


  • Now, how many of those 9-year olds like Superhero A?

Look at the cell under Superhero A & beside 9-year old. We see that it is \(0.375\)

So we would divide this by total, to get,

\(\frac{0.375}{1}=0.375\)

To convert decimal into percentage, we multiply the decimal with 100 and then tag along the "%" sign. Hence, we have:

\(0.375*100=37.5\)%
