QuestionJeanette has been baking all weekend for her school's bake sale. She used 12 ounces of sugar to bake brownies. Then, she used 12 more ounces of sugar to bake cupcakes. Finally, she used 8 ounces of sugar to make frosting for the cupcakes. How many pounds of sugar did she use in all?

Studdy Solution

STEP 1

What is this asking? How much sugar did Jeanette use, in *pounds*, after baking brownies, cupcakes, and making frosting? Watch out! The problem gives the amounts in *ounces*, but asks for the answer in *pounds*!
Don't forget to **convert**!

STEP 2

1. Calculate total ounces
2. Convert to pounds

STEP 3

Alright, let's **add up** all the sugar Jeanette used!
She used 1212 ounces for the **brownies**, 1212 ounces for the **cupcakes**, and 88 ounces for the **frosting**.

STEP 4

So, the **total** amount of sugar in ounces is 12+12+812 + 12 + 8.

STEP 5

Let's break it down. 12+12=2412 + 12 = 24, and then 24+8=3224 + 8 = 32.
That's **3232 ounces** of sugar!

STEP 6

Now, we need to convert those **3232 ounces** to pounds.
Remember, there are **1616 ounces** in **11 pound**.

STEP 7

To convert from ounces to pounds, we **divide** the number of ounces by 1616.
Think of it like this: each group of 1616 ounces makes 11 pound.
How many groups of 1616 can we make out of 3232?

STEP 8

So, we have 3216\frac{32}{16}.
We can simplify this fraction by dividing both the **numerator** and the **denominator** by their greatest common factor, which is 1616.
So, 3216=32÷1616÷16=21=2\frac{32}{16} = \frac{32 \div 16}{16 \div 16} = \frac{2}{1} = 2.

STEP 9

Therefore, Jeanette used **22 pounds** of sugar.

STEP 10

Jeanette used a total of **22 pounds** of sugar for all her baking.
