1
2
cups. Using what you know of whole numbers and what you know of fractions, complete the explanation for how you could double that mixed number.
If you double 4, it becomes
8
. If you double
1
2
, it becomes 1. Add 8 + 1 =
9
.
I DIDNT GET THAT MUCH COULD YOU EXPLAIN IT A LITTLE BETTER
To double the amount of rhubarb in the original recipe, you first double the whole number part, which is 4. When you double 4, it becomes 8. Then, for the fraction part, you double the numerator, which is 1. When you double 1, it becomes 2. So, the fraction part becomes 2/2, which can be simplified to 1. Lastly, you add the doubled whole number (8) to the fraction (1), which gives you a new amount of 9 cups of rhubarb in the doubled recipe.
Now, let's move on to the other ingredients:
1. Oranges: In the original recipe, there are 2 9 sections. To double this amount, you double the whole number part, which is 2. When you double 2, it becomes 4. The fraction part remains the same, which is 9. So, the new amount of oranges is 4 9 sections.
2. Apples: In the original recipe, there is 1 4 diced apple. To double this amount, you double the whole number part, which is 1. When you double 1, it becomes 2. The fraction part remains the same, which is 4. So, the new amount of apples is 2 4 diced apples.
3. Blueberries: In the original recipe, there is 1 5 cup of fresh blueberries. To double this amount, you double the whole number part, which is 1. When you double 1, it becomes 2. The fraction part remains the same, which is 5. So, the new amount of blueberries is 2 5 cups.
4. Peaches: In the original recipe, there are 5 9 slices of peach. To double this amount, you double the whole number part, which is 5. When you double 5, it becomes 10. The fraction part remains the same, which is 9. So, the new amount of peaches is 10 9 slices.
Therefore, the new amounts for oranges, apples, blueberries, and peaches in the doubled recipe are:
- Oranges: 4 9 sections
- Apples: 2 4 diced apples
- Blueberries: 2 5 cups
- Peaches: 10 9 slices
