Question

a truck engines need 3 1/4 gallons of oil for an oil change.write this number as an improper fraction

Answer 1

Multiply your whole number (which is 3 in this case) by your denominator (which is 4 in this case) and then add that new number to your numerator.
For example, if I wanted to turn 2 1/5 into an improper fraction, I would first do 2 x 5 = 10. Then, I would add 1 + 10 = 11.
So my improper fraction would be 11/5. Try the same method for your question.
