Hello everybody! I am Ms. Signorello and in today’s lesson we will work on some math skills, vocabulary, sentence completions, and writing exercises.

Today’s Math Skills

More on Fractions

Reciprocals

Factors and Multiples

more on fractions
More on Fractions

Alternating between a decimal and a fraction is an important skill.

To change a fraction into a decimal you simply divide the top number by the bottom number.

examples
Examples

Let’s say you want to change 4/5 to a decimal. You will divide 5 into 4.

Or you can use a calculator

Online Calculator

Let’s try the online calculator to convert 7/5 to a decimal.

Let’s change .275 to a fraction.

.275 = 275/1000 = 11/40

Let’s change .125 to a fraction.

On the calculator there’s a key that has

We’ll use that key and then enter in our decimal.

reciprocals
Reciprocals

Using reciprocals is an important skill for solving algebraic equations.

If you multiply a number by it’s reciprocal, it will always equal 1.

scientific notation
Scientific Notation

Suppose you need to change 345 to scientific notation. The number 345 is the same as

300 + 40 + 5. It can also be written as 3 x 100 + 4 x 10 + 5 x 1 =

factors
Factors

Factors are the positive integers that divide evenly into a number. For example the factors of 36 are:

36, 18, 12, 9, 6, 4, 3, 2, 1

I can divide 36 by any of these numbers and there will not be a remainder.

multiples
Multiples

Multiples are numbers that can be divided by the given number evenly. That means there is no remainder.

For example, the numbers 9, 18, 36, 45, and 54 are multiples of 9. 9 divides evenly into each of those numbers.

examples2
Examples

5A is divisible by both 2 and 3. If A is a digit, what is the value of A?

1

2

3

4

5

example
Example

If a - b is a multiple of 5, then which of the following must also be a multiple of 5?

b - a

a + b

ab

b - a 2

a + b 2

solution
Solution

If a - b is a multiple of 5, we can pick a number for a and a number for b that makes this true. Let a = 13 and b = 8. So, 13 - 8 = 5, which is divisible by 5. We will substitute a = 13 and b = 8 in the answer choices.

substituting
Substituting

8 - 13 = -5

  • b - a
  • a + b
  • ab
  • b - a 2
  • a + b 2

13 + 8 = 21

(13)(8) = 104

8 - 13

2

= -5 2

13 + 8 2

= 21 2

example1
Example

Which of the following could be remainders when 3 consecutive positive integers are each divided by 4?

1, 2, 3

0, 3, 2

3, 0, 1

3, 2, 1

0, 1, 2

solution1
Solution

Pick any 3 consecutive integers, say 7, 8, and 9. Now divide each of those by 4 and record the remainder for each division.

7/4 has a remainder of 3.

8/4 has a remainder of 0.

9/4 has a remainder of 1.

Therefore, answer c is the correct answer!
