One box contains a total grain weight of 512 grams. One grain weighs 56 grams. How many grains are in the box?

A) [tex]9 \frac{1}{8}[/tex]

B) [tex]9 \frac{8}{56}[/tex]

C) [tex]9 \frac{1}{4}[/tex]

D) [tex]9 \frac{8}{512}[/tex]

Answer :

Sure! Let's solve this question step-by-step:

1. Identify the Known Values:
- Total weight of grains in the box: 512 grams.
- Weight of one grain: 56 grams.

2. Determine the Number of Whole Grains:
- To find the number of whole grains, divide the total weight of grains by the weight of one grain.
- [tex]\( \text{Number of whole grains} = \frac{512}{56} \)[/tex].
- This division results in approximately 9.142857142857142, which means there are 9 whole grains.

3. Calculate the Fractional Part:
- After determining the whole grains, you need to find the remainder or the fractional part of the grains.
- The remainder from the division [tex]\( 512 \, \text{mod} \, 56 \)[/tex] is 8.

4. Formulate the Mixed Number:
- The result gives us 9 whole grains and a remainder that can form a fraction.
- The fraction formed by the remainder is [tex]\( \frac{8}{56} \)[/tex].
- Simplify [tex]\( \frac{8}{56} \)[/tex] to [tex]\( \frac{1}{7} \)[/tex].

5. Combine Whole and Fractional Part:
- Therefore, the number of grains in the box is [tex]\( 9 \frac{1}{7} \)[/tex].

Looking at the given options, none of them matches exactly with [tex]\( 9 \frac{1}{7} \)[/tex], suggesting a slight difference in interpretation or simplification in the available choices.

Please take into consideration that the Python answer provided a direct calculation leading to this understanding, but for the choices given, the closest choice to the approximate calculation and the unique fraction provided is considered.
