Express 0.537 as a percentage.
We know that, in order to convert a
percentage into a decimal, we need to divide by 100, as the word “percent” means out
of 100. This means that, in order to
convert from a decimal to a percentage, we need to multiply by 100, as multiplying
is the inverse operation of dividing. In this question, we need to
multiply 0.537 by 100. Multiplying by 10 moves all our
digits one place to the left. So multiplying by 100 moves them
two places to the left. 0.537 multiplied by 100 is
53.7. Our decimal expressed as a
percentage is 53.7 percent.
This method can be used to convert
any decimal into a percentage. We also recall that any decimal
that has a zero in front of the decimal point will be less than 100 percent.
