Circle the fraction which is
equivalent to 43.75 percent. The options are three-eighths,
seven sixteenths, one-quarter, or three-sevenths.

To answer this question, we need to
convert all of the numbers to a common form. And in this case, it’s going to be
easiest to convert them all to decimals. Let’s begin with 43.75 percent. Percent literally means out of
100. So 43.75 percent means 43.75 out of
100. We can express this as a fraction;
it’s 43.75 over 100.

Now remember, we want to compare
this to the other numbers, all of which are fractions. But, it isn’t going to be easy to
do this as some of the fractions have denominators which are not factors of 100. So this is why we’re going to
convert them all to decimals. Remember that the horizontal line
between the numerator and denominator in a fraction means divide. So this means 43.75 divided by 100
which is 0.4375.

We do have a calculator to help
with this but in a non-calculator exam, we could just remember that the decimal
point would stay fixed and all of the digits move two places to the right when
dividing by 100. So we’ve worked out what 43.75
percent is equal to as a decimal. Let’s look back at the other
fractions.

We can eliminate some of the
possibilities straightaway. Perhaps, you know that one-quarter
is equal to 0.25 as a decimal or 25 percent. So one-quarter is not equivalent to
43.75 percent. You may also know that the fraction
three-eighths is equivalent to 0.375 as a decimal. So we can also eliminate
three-eighths. But, if you didn’t know this, you
could work it out by dividing three by eight on your calculator.

Let’s look at the final two
possibilities for which you probably don’t know the decimal equivalents of by
heart. To work these out, we need to
divide each numerator by the denominator. So that’s seven divided by 16 and
three divided by seven. Seven divided by 16 is 0.4375. And three divided by seven is
0.428571 recurring. The dots over the first and last
digits after the decimal point indicates that all six digits recur. So of the four options, the only
fraction which is equivalent to 0.4375, and therefore 43.75 percent, is seven
sixteenths.
