On Sunday, Sheldon bought 4 ½ kg of plant food. He used 1 ⅔ kg on his strawberry plants and ¼ kg for his tomato plants. How many kilograms of plant food did Sheldon have left? (Question 4A) Sheldon wants to feed his strawberry plants 2 more times and his tomato plants one more time. He will use the same amounts of plant food as before. How much plant food will he need? Does he have enough left to do so? (Question 4B) And 2/3+3/4 also lol
4 1/2 - 1 2/3 - 1/4 = ___
1 2/3 * 2 + 1/4 = ___
Can somebody give a full step by step explanation on how to do the whole thing? Also can they fully explain how they got it as well?
I don’t need sleep I need answers (or just an equation, maybe not the answer itself)
On Sunday, Sheldon bought 4 1/2 kg of plant food. He used 1 2/3 kg on his strawberry plants and used 1/4 kg for his tomato plants. How many kilograms of plant food did Sheldon have left? Write one or more equations to show how you reached your answer.
2 7/12
To solve Question 4A, we need to subtract the amounts of plant food Sheldon used from the total amount he had. Sheldon bought 4 ½ kg of plant food, which is equivalent to 4 kg and 500 grams.
He used 1 ⅔ kg of plant food for his strawberry plants, which is equivalent to 1 kg and 666 grams.
To subtract 1 ⅔ kg from 4 kg, 500 g, we can convert both to grams and then subtract:
4 kg (or 4,000 g) - 1 kg, 666 g = 4,000 g - 1,666 g = 2,334 g.
Next, he used ¼ kg of plant food for his tomato plants, which is equivalent to 250 grams.
So, to find out how much plant food Sheldon has left, we subtract 250 g from 2,334 g:
2,334 g - 250 g = 2,084 g.
Therefore, Sheldon has 2,084 grams of plant food left, which is equivalent to 2 kg and 84 grams.
Now, for Question 4B, Sheldon wants to feed his strawberry plants 2 more times and his tomato plants one more time. Since he used the same amount of plant food previously, we need to calculate how much plant food he will need for each type of plant and then check if he has enough left.
For the strawberry plants, he used 1 ⅔ kg per time. Multiply this by 2 to calculate the total amount needed:
1 ⅔ kg * 2 = 3 ⅓ kg.
For the tomato plants, he used ¼ kg per time. Multiply this by 1 to calculate the total amount needed:
¼ kg * 1 = ¼ kg.
To determine if he has enough plant food left, we need to subtract the total amount needed from the amount he has left:
2 kg, 84 g - (3 ⅓ kg + ¼ kg).
To subtract mixed numbers, convert them to improper fractions first:
3 ⅓ = 10/3 and ¼ = 1/4.
Now, we can subtract the fractions:
2 kg, 84 g - (10/3 kg + 1/4 kg).
To add and subtract fractions, we need a common denominator. In this case, the common denominator is 12:
2 kg, 84 g - (40/12 kg + 3/12 kg).
Now, we can subtract the fractions using the common denominator:
2 kg, 84 g - 43/12 kg.
To subtract fractions, we need to have like denominators. Convert 2 kg to grams (2,000 g) and add to the grams portion:
2,000 g + 84 g = 2,084 g.
Now, we can subtract the fractions with like denominators:
2,084 g - 43/12 kg.
To convert 43/12 kg to grams, multiply the fraction by 1,000 (since 1 kg = 1,000 g):
43/12 kg * 1,000 g/kg = 3,583 g.
Finally, subtract the converted fraction from the grams:
2,084 g - 3,583 g = -1,499 g.
Therefore, Sheldon does not have enough plant food left to feed his strawberry plants 2 more times and his tomato plants one more time.
Lastly, to solve the equation 2/3 + 3/4, we need to find a common denominator:
The common denominator for 3 and 4 is 12.
Now, we can rewrite the fractions with the common denominator:
2/3 = 8/12 and 3/4 = 9/12.
To add the fractions, simply add their numerators:
8/12 + 9/12 = 17/12.
Therefore, 2/3 + 3/4 is equal to 17/12 or 1 5/12.
