Mrs Gutierrez ordered 1 cheese pizza, 1 pepperoni pizza, and 1 sausage pizza. Each pizza is cut into 12 pieces. The students are 10/12 of the cheese pizza, 9/12 of the pepperoni pizza, and 3/12 of the sausage pizza. What fraction of all the pizza is left?

1 whole or 12/12

Step-by-step explanation:

so you go and subtract and you ad what each one equals

                                       10-12=2

                                         9-12=3

                                         3-12=9

                                      =  1 whole OR 12/12

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
