Multiplication and Division Equations with Decimals Honors Math – Grade 6

2
Problem of the Day Carl and his friends made a paper-clip chain 8.05 km long. The world record, however, is 32.2 km! How many times greater than the length of Carls chain is the length of the worlds-record chain? What are the important facts? Write an equation to show the original depth. Define a variable first! Lets take a closer look…

3
KEY CONCEPT Solving Multiplication Equations RECALL: To solve a multiplication equation, we use the inverse operationdivision. This is known as The Division Property of Equality. The length of the worlds-record chain is 4 times greater than Carls chain.

4
Solve each equation. Do not forget the rules for dividing signed decimals…quotient of like signs is positive, quotient of unlike signs is negative.

5
Solve each equation. Do not forget the rules for dividing signed decimals…quotient of like signs is positive, quotient of unlike signs is negative.

6
Solve each equation. Do not forget the rules for dividing signed decimals…quotient of like signs is positive, quotient of unlike signs is negative.

7
KEY CONCEPT Solving Division Equations RECALL: To solve a division equation, we use the inverse operationmultiplication. This is known as The Multiplication Property of Equality. Do not forget the rules for multiplying signed decimals…product of like signs is positive; product of unlike signs is negative!

8
Solve each equation. Do not forget the rules for multiplying signed decimals…product of like signs is positive; product of unlike signs is negative!

9
Solve each equation. Do not forget the rules for multiplying signed decimals…product of like signs is positive; product of unlike signs is negative!

11
KEY CONCEPT Combining Like Algebraic Terms Sometimes you need to combine like terms before solving an equation. To combine like algebraic terms, add or subtract the coefficients.

12
Solve each equation. First combine like terms then solve the equation using inverse operations.
