Subtract 24% from your 100% (equal to 120 cm) and you get 76%. Now find 76% of 120 cm. Multiply 120 by 0.76 and you get 91.2 cm.
The rule is: Before you can add or subtract fractions, they must have
the same denominator.
For this little problem, don't worry about the signs yet. Just make both
fractions have the same denominator. I suggest you change the first one
to something over 250.
When your fractions have the same denominator, you get the sum or difference
like this:
-- The numerator of the answer is the sum or difference of the two numerators.
-- The denominator of the answer is the same as the denominator of the two fractions.
The formula for finding the area of a circle is A=pi(r^2). In this problem, you do 3.14 x 23^2.
3.14 x 23^2--->3.14 x 529--->1661.06 yards.
