Answer:

4/5

Step-by-step explanation:

The wording is ambiguous, as it often is when math expressions are described in English. We assume you intend ...

$\dfrac{3n+8}{n+7}=\dfrac{4}{3}\\\\3(3n+8)=4(n+7)\qquad\text{multiply by $3(n+7)$}\\\\9n+24=4n+28\qquad\text{eliminate parentheses}\\\\5n=4\qquad\text{subtract $4n+24$}\\\\\boxed{n=\dfrac{4}{5}}\qquad\text{divide by 5}$

The number is 4/5.

Reduce 10/20 please i need help I am not really good at reducing lol

STALIN [3.7K]

If you have 10/20, you need to find a common number that goes into them, in this case it can be 5. divide both numbers by 5 and you will get 2/4, now divide that by 2 because 2 goes into 2 and 4, and you get 1/2.
Hope this helps!
