turn it into an improper fraction. you multiply the whole number by the denominator then add the numerator, leaving it over the original denominator. eg/ 2×4= 8 +3 = 11/4 1×2= 2 +1 = 3/4
find a common denominator. eg/ 2 and 4 have the common denominator of 4.
then you make the denominators the same. eg/ 3/2 × 2 = 6/4
First convert 7.5 meters to 750cm, then use your formula A=1/2bh and pop it in your calculator: (1/2)(750)(6) and be sure to include cm as the unit of measurement in your final answer.
