Math brainiest NEEDED. its the bottom half and please explain your answer

1) The expressions are not equivalent. When you expand and multiply 2(x + 3) it becomes 2x + 6. This is not equal to 3x + 5

2) They are equivalent. Again, expand and multiply the second expression. 2(3n + 4) becomes 6n + 8. This makes both sides equal.

3) They are equivalent. In the parentheses, you are adding 3 y's and a 2. This gives you 3y + 2. Now add the additional 3y that follows the closed parentheses. You'll have 6y + 2. Now both sides are equivalent.

If the numerator is greater than or equal to the denominator, the fraction is called an improper fraction.

A mixed fraction is the sum of a whole number and a fraction.

To simplify a fraction is to convert it into a form which the numerator and denominator have no common factor other than one.
