Homework Statement
Calculate: (3 a + 3 b)/(a - b) If a/b = 2/5
No attempts, I don't know how to solve this.
Help?

A ratio is a comparison of two quantities or values. It represents how many times one value is contained within another value. It is typically written in the form of a fraction or with a colon between the two values.
To solve a ratio question, you need to set up an equation where the ratio is equal to the given values. In this case, the equation would be (3a + 3b)/(a - b) = 2/5. Then, you can simplify the equation and solve for the unknown values.
This means that there are 2 parts of a for every 5 parts of b. It is a way to express the relationship between two values in terms of a fraction.
To simplify fractions, you need to find the greatest common factor (GCF) of the numerator and denominator and divide both by it. In this case, the GCF of 3a and a is a, and the GCF of 3b and b is b. So, the simplified fraction would be 3/5.
Yes, you can still solve the ratio question without knowing the specific values of a and b. You can use variables to represent the values and solve the equation algebraically to find the ratio.
