Question

(a) write 0.524 as a percentage.
(b) write 7.4% as a decimal.
(a) 0.524 = square %
(b) 7.4% = square

Explanation:

Part (a)

Step1: Convert decimal to percentage

To convert a decimal to a percentage, multiply by 100 and add the % sign. So, for \( 0.524 \), we do \( 0.524\times100 \).
\( 0.524\times100 = 52.4 \)

Step2: Add the percentage sign

So \( 0.524 = 52.4\% \)

Part (b)

Step1: Convert percentage to decimal

To convert a percentage to a decimal, divide by 100 (or move the decimal point two places to the left). For \( 7.4\% \), we do \( 7.4\div100 \).
\( 7.4\div100 = 0.074 \)

Answer:

s:
(a) \( 52.4\% \)
(b) \( 0.074 \)
