Answer 2

67.1

Explanation:

Writing the statement '49 is 73% of what number?' where x is the number we are trying to find:

`49 = 73\% \: of \: x`

To find the percentage of a number, we multiply the number by the decimal equivalent of the percentage, so can be rewritten as:

`49 = (73)/(100) * x`

`49 = 0.73x`

`(49)/(0.73) = x`

`x = 67.1 \: rounded \: to \: 3 \: signifiant \: figures`
