Question

(a) write 67.98% as a decimal.
(b) write 1.6 as a percentage.
(a) 67.98% =
(b) 1.6 = %

Explanation:

Part (a)

Step1: Recall percentage to decimal conversion

To convert a percentage to a decimal, we divide by 100 (or move the decimal point two places to the left).
$$67.98\%=\frac{67.98}{100}$$

Step2: Perform the division

Dividing 67.98 by 100 gives:
$$\frac{67.98}{100} = 0.6798$$

Step1: Recall decimal to percentage conversion

To convert a decimal to a percentage, we multiply by 100 (or move the decimal point two places to the right).
$$1.6\times100$$

Step2: Perform the multiplication

Multiplying 1.6 by 100 gives:
$$1.6\times100 = 160$$
So, \(1.6 = 160\%\)

Answer:

0.6798
