Question

(a) write 257% as a decimal.
(b) write 0.003 as a percentage.
(a) 257% =
(b) 0.003 = %

Explanation:

Step1: Convert percentage to decimal (part a)

To convert a percentage to a decimal, we divide by 100 (or move the decimal point two places to the left). For \(257\%\), we do \(257\div100\).
\(257\div100 = 2.57\)

Step2: Convert decimal to percentage (part b)

To convert a decimal to a percentage, we multiply by 100 (or move the decimal point two places to the right). For \(0.003\), we do \(0.003\times100\).
\(0.003\times100 = 0.3\)

Answer:

(a) \(2.57\)
(b) \(0.3\)
