Question

(a) write 0.027 as a percentage.
(b) write 5.34% as a decimal.
(a) 0.027 = □%
(b) 5.34% = □

Explanation:

Part (a)

Step1: Recall the conversion rule (decimal to percentage: multiply by 100)

To convert a decimal to a percentage, we multiply the decimal by 100 (or move the decimal point two places to the right).
For \( 0.027 \), we do \( 0.027\times100 \).

Step2: Perform the multiplication

\( 0.027\times100 = 2.7 \)

Part (b)

Step1: Recall the conversion rule (percentage to decimal: divide by 100)

To convert a percentage to a decimal, we divide the percentage value by 100 (or move the decimal point two places to the left).
For \( 5.34\% \), we do \( 5.34\div100 \).

Step2: Perform the division

\( 5.34\div100 = 0.0534 \)

Answer:

(a) \( 2.7\% \)
(b) \( 0.0534 \)
