CONTENT OF THE LESSON

FOCUS LESSON – INTRODUCTION

PUPIL’S ACTIVITIES

The teacher asks the pupils what decimals he had learnt

Sample 1

0.3

= 3/10

0.17

= 17/100

1.6

= 16/10

= 1 6/10

Sample 2

1/2

= 0.5

5/10

= 0.5

1/4

= 0.25

Sample 3 – decimals multiplying and dividing tens of right numbers

Sample 4

0.3 × 5 = 1.5

3/10 × 5

= 15/10

= 1.5

0.45 × 6

= 2.7

45/100 × 6

= 270/100

= 2.70

Sample 5 – to multiply display of right numbers

0.45 × 10

= 4.5

0.45 × 100

= 45

4.5 × 10

= 45

0.6 × 1000

= 600

6.03 × 100

= 603

0.007 × 1000

= 7

When we move to the decimal to the right side, zeros and add the zero, for the right of 45, 600, 603, 7

PUPIL’S ACTIVITIES:

EXERCISE ONE – Multiplication of Three fractions

Complete the fractions:

1. Change these results into fractions following:

1. a) 0.6 = /
2. b) Express the fraction below and convert it to lowest terms:

1. 25/100 = /

1. c) Express 7: Main Fractions:

/ = /

EXERCISE TWO

Complete each of the following and express in lowest terms:

1. 0.7 = /
2. 0.09 = /

/ = /

Exercise 3 – Expressing whole numbers

4/5 × 100

= 400/5

= 80

24/8

= 3

Exercise 4

7 × 1/7

= 7/7

= 1

Exercise 4

Examples:

4 1/2 × 3 = 7/2

= 1/2 × 3 = 3/2

= 13.5

Sample 5 – multiplication of fractions to right numbers

Examples 4:

1. Common fractions: Use the appropriate.
2. 1/3 × 6

Sample: Factors allow fractions to change their base properly.

1/3 × 6

= 6/3

= 2

1 1/4 × 2 = 1 × 1/4 × 2 = fractions allow the pupils some focus you allow with the class set to make proper fractions to convert.

5/4 × 2

= 10/4

= 2 1/2

3 1/2 × 2 = 1 × 1/2 × 2

= 7/2 × 2

= 14/2

= 7

3 × 2 1/3

= 3 × 7/3

= 21/3

= 7
