Answer:
300 x 1/10 = 30 and 30 divided by 1/10 is 300
Explanation:
You know 30 is 1/10 of 300 because 300 times 1/10 is 30
![300*(1)/(10) = (300)/(10) =30](https://img.qammunity.org/2020/formulas/mathematics/middle-school/myskvdw5lm5ob4v9llipy1owvhbucbh7tv.png)
^Here you multiply 300 times 1/10, meaning 300/1 times 1/10, and so you multiply the numerator times the numerator and the denominator times the denominator...
Also, if you divide 30 times 1/10 (0.1) it will equal 300.
