You are making cookies for a large party and need to triple the recipe. (You do this

iren [92.7K]

Answer:

Here's what I get.

Step-by-step explanation:

To triple this recipe, you must know that

3 × ¼ = ¾

3 × ⅔ = ⁶/₃ = 2

3 × ½ = ³/₂ = 1½

Then the triple recipe will read

$\begin{array}{llll}1\frac{3}{4} & \text{cups} & \text{peanut butter}&\\5 & \text{cups} & \text{sugar}& 3 \times 1\frac{2}{3} = 3 + 2\\1\frac{1}{2} & \text{tsp} & \text{salt}&\\7\frac{1}{2}& \text{cups} & \text{flour}& 3 \times 2\frac{1}{2} = 6 + 1\frac{1}{2} \\\,\frac{3}{4} & \text{cup} & \text{butter}&\\4\frac{1}{2} & \text{tsp} & \text{vanilla}&3 \times 1\frac{1}{2} = 3 + 1\frac{1}{2}\\\end{array}$
