Shawn, Ryan, and Dominic ate a whole pizza. Shawn ate 1/6 of the pizza, Ryan at 1/2 of the pizza and Dominic ate the rest how much pizza did Dominic eat

Dominic ate  of the pizza.

Step-by-step explanation:

First you want to convert the fractions so they all have the same denominator (bottom number in the fraction.) That will make it a lot easier to add and subtract with them.

=

So Shawn ate 1/6 of the pizza, and Ryan ate 3/6 of the pizza. To find what else makes up the whole pizza (what Dominic ate) we add 1/6 and 3/6, then subtract from the whole.

+ =

- =

Therefore Dominic ate  of the pizza.

do you have the measurements?

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
