Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced problems involving fractions.

We are asked to find at least one common denominator for the group of numerators. The most obvious thing we can see that all 4 numbers have in common is that they are all even numbers. Therefore we know that at least one common denominator will be 2. Since all even numbers are divisible by 2 with no remainders.

I hope this answered your question. If you have any more questions feel free to ask away at .

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

it is 10.6 according to my calculations
