2.5/300 × 12/x
Excellent work Fluffykatelyn
Question asker please note :)
$$1/10x=\frac{1}{10}\times x = \frac{x}{10}$$
1. Simply multiply the numerators and the denominators of both fractions by doing 2.5 times 12 over 300 times x.
This gives you 30/300x.
2. Now simplify the fraction and you'll get 1/10x :)
Hope this helped!
