vernald ordered 12 1/4 kilograms of apples, unfortunately 3/7 of the apples were bruised and unusable.
how many kilograms of good apples did vernald have to make his apple pie
To find out how many kilograms of good apples Vernald had, we can first calculate the weight of the bruised apples and then subtract it from the total weight of the apples.
1. Let's start by finding the weight of the bruised apples:
- Vernald ordered 12 1/4 kilograms of apples, which is equivalent to 12 + 1/4 = 49/4 kilograms.
- To find 3/7 of the apples, we multiply 49/4 by 3/7:
(49/4) * (3/7) = (49 * 3) / (4 * 7) = 147/28 kilograms.
2. Next, we subtract the weight of the bruised apples from the total weight of the apples:
Total weight of the apples - Weight of the bruised apples = Good apples
(49/4) - (147/28) = (49/4) - (147/28)
To perform this subtraction, we need to have a common denominator, which is 28:
(49/4) - (147/28) = (49/4) - (21/4)
Now, we can subtract:
(49/4) - (21/4) = 28/4 = 7 kilograms.
Therefore, Vernald had 7 kilograms of good apples to make his apple pie.
To find out how many kilograms of good apples Vernald had, we need to subtract the weight of bruised apples from the total weight of apples he ordered.
1. Start by converting the mixed number 12 1/4 kilograms into an improper fraction:
12 1/4 = (12 * 4 + 1) / 4 = 49/4 kilograms.
2. Now we need to calculate the weight of the bruised apples. Since 3/7 of the apples were bruised, we can multiply the total weight by 3/7:
Weight of bruised apples = (49/4) * (3/7) = (49 * 3) / (4 * 7) = 147/28 kilograms.
3. Finally, to find the weight of good apples, subtract the weight of bruised apples from the total weight:
Weight of good apples = (49/4) - (147/28) = (49/4) - (147/28) = (49 * 7 - 147) / 28 = 343/28 kilograms.
Therefore, Vernald had 343/28 kilograms of good apples to make his apple pie.
7/7 total - 3/7 bad = 4/7 good
(4/7)*(49/4) = 49/7 which we all know is7
Well, looks like Vernald's pie won't be as appley as he hoped! Let's crunch the numbers.
Vernald ordered 12 1/4 kilograms of apples, and unfortunately, 3/7 of them were bruised. So, to find out how many good apples he had, we need to subtract the bruised ones.
First, let's convert 12 1/4 kilograms to a common fraction. 12 is the same as 48/4, and when you add 48/4 to 1/4, you get 49/4 kilograms of apples.
Now, we need to find 3/7 of 49/4. To do that, we multiply the numerators (3 x 49) to get 147, and multiply the denominators (7 x 4) to get 28. So, 3/7 of 49/4 is 147/28 kilograms of unusable apples.
To find out how many good apples Vernald had, we need to subtract 147/28 from 49/4. To do that, we need to find a common denominator, which is 28. Converting 49/4 to a fraction with a denominator of 28 gives us 147/28.
Now, we do some fancy math by subtracting: 147/28 - 147/28.
Since they have the same denominators, we can simply subtract the numerators: 147 - 147 = 0. Uh-oh, it seems poor Vernald had zero kilograms of good apples left. I guess his apple pie dreams have gone up in smoke.
