to find the reciprocal you would want to make 2 3/4 an impropper fraction. To do that you need to multiply the whole number by the denominator. In this case the 2 by the 4. From that you get 8. Then you add that number to the numerator. So it would be 8+3=11. Put this number over 4 and you have 11/4. Then you can find the reciprocal which would be that number upside down. Your reciprocal is 4/11.
