Laila pours some rice into a pan to cook for supper. For every 1 cup of uncooked rice, she needs to use 2 cups of water. Which equation could be used to find the amount of water, w, she should use to cook r cups of rice?

w=2r

Step-by-step explanation:

so let say the amount of water is y instead of w and the cup of rice is x instead of r.

so if we were to create a table we use the numbers given

x     y

1      2      so as the cup of rice increase by 1 cup the amount of water increase

2     4       by two.

3       6       so we know the slope is 2/1 so  the equation is w=2r  

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
