Understanding Percentages and Conversions: A Practical Example from kg to gms

Many common questions in mathematics can be tricky, especially when they test your understanding of units and conversions. One such question is what percent of 91 grams is 6.5 kilograms. Let's break this down step-by-step to understand the solution.

Converting Kilograms to Grams

The first step involves understanding the basic equivalence between kilograms and grams. It is essential to remember that 1 kilogram (kg) is equal to 1000 grams (gms). Therefore, when converting 6.5 kilograms to grams, we multiply 6.5 by 1000:

6.5 kg 6.5 x 1000 g 6500 grams

Expressing as a Percentage

Next, we need to express 91 grams as a percentage of 6500 grams. To do this, you can use the following formula:

(part/whole) x 100 percentage

In this case, the part is 91 grams and the whole is 6500 grams. So, we calculate the percentage as follows:

(91 / 6500) x 100 0.014 x 100 1.4%

Therefore, 91 grams is 1.4% of 6500 grams.

Alternative Method: Working Backwards

If you prefer to work backwards, you can reframe the problem as follows:

91 grams 0.091 kg

Given:

0.091 kg - X

And we are given 6.5 kg to find X:

6.5 kg - X

To find X, we use the proportion:

X (6.5 / 0.091) ≈ 71.4286

Therefore, 91 grams is approximately 71.4286% of 6500 grams.

Conclusion

Understanding how to convert between kilograms and grams and how to calculate percentages is crucial in many real-world applications, including finance, health, and everyday measurements. The key is to remember the basic equivalences and apply the correct mathematical operations.
