1. In box of 48 apples 1 in every 6 apples is rotten. How many rotten apples are?
2. There are 8 puppies for sale. There are 6 spotted puppies and 2 solid puppies. What is the ratio of solid to spotted puppies?
The answer to 1 is 8 because if you divide 48 by 6 you would get 8.
The answer to 2 is any of these 2:6, 2/6, or 2 to 6 because that is the ratio of spotted puppies to solid.

1.-3+7=?
2. -4-2=?
The answer to 2 is -6 because you have to change it to addition and use the sign which has more again.
Chapter 5
Chapter 5 is all about multiplying and dividing rational numbers. Here are two question examples from chapter 5.
1. (-3)x5=?
2. 56 divided by -8 is ?
Answers/explanation
The answer to 1 is -15 because if you just think of it as three groups of -5 that is the answer you would get.
The answer to 2 is -7 because all you do is just divide and if the numbers are the same its positive but if they are different it is negative.
Chapter 6
Chapter 6 is all about numerical and algebraic expressions and equations. Here are two question examples from chapter 6.
1. Evaluate this expression x-7 (If x = -11)
2. Simplify this expression 6x+9x
Answers/explanation
The answer to 1 is -18 because if you just plug in -11 and solve that is what you would get.
The answer to 2 is 15x because all you have to do is combine the like terms (add) and that will give you the answer.
Chapter 7
Chapter 7 is all about solving equations and inequalities. Here are two question examples from chapter 7.
1. 2+7x=16
2. 2x+5<-17
Answers/explanation
The answer to 1 is 2 because of my work shown.
The answer to 2 is -11 because of my work shown.
