Hoi!
If the two fractions have a common denominator, then yes, you do. Only add the numerators. :)
I have no idea how to answer that, sorry :(
Answer:
3
Step-by-step explanation:
In order to answer this question, we use the concept of ratio and proportion wherein we use the equation,
R1 / T2 = R2 / T1
where R is for rate and T is for time. Substituting the known values to the equation,
(600)/x = (400)/ 20
The value of x from the equation is 30. Thus, it will take 30 hours if the rate was adjusted to 400 gallons per minute.
False because the data would go more apart than closer
