Graham is making treat bags of mixed candy to give as favors at his sister’s birthday party. He has enough candy to make favors for all her friends as long as he keeps the ratio consistent. The ratio of the number of sour candies, C, to the number of sweet treats, T, is 4 : 1. Based on the ratio, select all true statements. To help you determine the correct statements, you may create a ratio table.

• The equation C=1/4T can be used to calculate the number of sour candies given the sweet treats.

• The equation T=1/4C can be used to calculate the number of sweet treats given the sour candies.

• If Graham put 24 sour candies in a bag, he should have 6 sweet treats in that bag.

• If Graham put 12 sweet treats in a bag, he should have 3 sour candies in that bag.

• The equation C=4T can be used to calculate the number of sour candies given the sweet treats.

To make a gallon of Kool-aid, Blayton adds 4 cups of kool-aid mix to every 2 cups of sugar.

Determine the ratio used for the cups of kool-aid mix to the cups of sugar. ____________

At a baseball game, the concession stand noticed that for every 3 hot dogs sold, they sold 5 hamburgers.

The ratio of the number of hot dogs sold to the number of hamburgers sold was _____________.

The format we use to write an equation with unit rate (k)

• y = k/x

• y = kx

• k = y/x

• k = xy

What is a Ratio?

• Is a comparison of two quantities 

• A rate with a denominator of one

• It is when the only factor the numerator and denominator share is a one 

• Two decimals that can be multiplied

An art project requires the class to use a lot of green paint. The students decide to use a ratio of 2 ounces of blue paint with every 3 ounces of yellow paint to create the shade of green they want.

Point B is 6 Blue and _______ Yellow.

Which equation describes the table? 

• y = 1/4x 

• y = 4 - x 

• y = 4 + x 

• y = 4x 

Which equation matches the table? Hint: Try an answer choice by substituting the x value from the table into one of the equations that is an answer choice. However if you sub an x value into the equation and the answer is NOT the matching y, you have just proven that it CANNOT be that equation for the correct answer.

• y = - (-x + 9)

• y = x + 9 

• y = 3x + 9

• y = 12x - 3
