Question

If the weight of $12$ sheets of thick paper is $40$ grams, how many sheets of the same paper would weigh $16\frac{2}{3}$ kilogram?

Answer 1

Number of sheets whose weight is $40g$ or $0.04kg=12$

Number of sheets whose weight is $1g$ or $0.001kg=\frac{12}{0.04}$

Number of sheets whose weight is $16\frac{2}{3}$ or $\frac{50}{3}kg=\frac{12}{0.04}\times \frac{50}{3}=300\times \frac{50}{3}=5000$

Number of sheets whose weight is $16\frac{2}{3}=5000$ sheets
