Errol has 8 cups of rice LEFT. His recipe needs 3/4 OF A CUP of rice. How many times can he make the recipe before he runs out of rice?
I know I should divide 8 and 3/4 and the answer is 32/3, so should I put it into a mixed number if so it would be 10 2/3, and the whole number is 10. So the answer is 10 because he can't make his recipe 1/2 it has to be a whole number?
look back at your previous post of this question.
To determine how many times Errol can make the recipe before running out of rice, we need to divide the number of cups of rice he has (8) by the amount needed for each recipe (3/4 cup).
To divide fractions, you can multiply the numerator (top number) of the first fraction (8) by the reciprocal of the second fraction (4/3).
Here's the step-by-step calculation:
8 ÷ (3/4)
= 8 × (4/3)
= (8 × 4) / 3
= 32 / 3
So, Errol can make the recipe 32/3 times.
To express the answer as a mixed number, we divide the numerator (32) by the denominator (3) and write the remainder as a fraction:
32 ÷ 3 = 10 remainder 2
This means Errol can make the recipe 10 times completely, with 2/3 of a cup of rice leftover.
Therefore, the correct answer is 10 times, not 10 2/3, because the recipe cannot be made partially.
To determine how many times Errol can make the recipe before he runs out of rice, you need to divide the amount of rice Errol has (which is 8 cups) by the amount of rice the recipe requires (which is 3/4 of a cup).
To divide a whole number (8) by a fraction (3/4), you can follow these steps:
Step 1: Convert the whole number to a fraction by putting it over 1: 8/1.
Step 2: Invert the fraction you need to divide by (3/4) to find its reciprocal, which is 4/3.
Step 3: Multiply the fractions: (8/1) * (4/3) = 32/3.
So when you divide 8 cups of rice by 3/4 cups per recipe, you get 32/3.
Now, to express this answer as a mixed number, you divide the numerator (32) by the denominator (3):
32 ÷ 3 = 10 with a remainder of 2.
The fraction part of the mixed number is the remainder (2) over the denominator (3): 2/3.
Therefore, the answer is 10 and 2/3. This means that Errol can make the recipe 10 times completely and have 2/3 of the rice left. Since the recipe cannot be made with a fraction of the rice, the final answer would be 10 times.
