Question

write 28.5% as a decimal
write 0.4 as a percentage

Answer 1

To convert 28.5% to a decimal, divide by 100:

\[
28.5\% = \frac{28.5}{100} = 0.285
\]

To convert 0.4 to a percentage, multiply by 100:

\[
0.4 = 0.4 \times 100 = 40\%
\]

So, 28.5% as a decimal is 0.285, and 0.4 as a percentage is 40%.
