Definition of Quantitative Reasoning 

Quantitative Reasoning is the use of basic mathematical knowledge and operations to solve problems. These problems are invariably related to how real-life issues are solved.

Steps to Solving Quantitative Reasoning Examples

Quantitative reasoning requires basic mathematical knowledge to solve it correctly. Therefore, primary school pupils should be taught the basis of math problems. 

These foundational knowledge include;

• Addition
• Subtraction
• Multiplication 
• Division
• Algebraic processes
• Squares and Square roots 

Is Quantitative Reasoning Hard?

Quantitative reasoning requires the use of Mathematical knowledge. When children at the primary school level understand the foundational Mathematics, they will solve Quantitative Reasoning with ease.

Hence, quantitative reasoning is easy, it students understand the basics.

Lantern Step Exercise 5b

Equivalent fractions

Using example 1

 

3 × 2= 6

5 × 2= 10

Answer 6/10

To get ⅗

6÷2= 3

10÷2= 5

Answer ⅗

 Lantern Steps Exercise 5c

Using Example 2

To get 15

3 × 5= 15

To get 3

15 ÷ 5 = 5

To get 5

15 ÷ 3 = 5

To get 20

15+5=20

To get 18

15 + 3 = 18

Lantern Steps Exercise 6a

Using Example 1

To get 29.67cm

18.22cm + 11.45cm = 29.67cm

To get 18.22cm

29.67cm – 11.45cm = 18.22cm

To get 11.45cm

29.67cm – 18.22cm = 11.45cm

Using Example 2

To Get 23.98kg

14.28kg + 9.70kg = 23.98kg

To Get 14.28kg

23.98kg – 9.70kg= 14.28kg

To Get 9.70kg

23.98 – 14.28kg = 9.70kg

 

 

Lantern Step Exercise 6c

Using example 2

The diagram indicates equivalent fractions

6 × 3 = 18

9 × 2 = 18

To get 3

18÷6= 3

To get 9

18÷2= 9

To Get 6

18 ÷ 3= 6

To Get 2

18 ÷ 9 = 2

Lantern Step Exercise 7a

Using Example 1

To Get 1800

150 × 12= 1800.

To Get 150

1800 ÷ 12 = 150

To Get 12

1800 ÷ 150= 12

Using Example 2

To Get 2000

200 × 10= 2000.

To Get 200

2000 ÷ 10 = 200

To Get 10

2000 ÷ 20= 10

Lantern Step Exercise 7b

Using Example 3

To Get 30

5 × 4 = 20( upper numbers)

5 × 2 = 10(lower numbers)

20 + 10= 30

To Get 5(up)

5 × 2= 10

30 – 10 = 20

20 ÷ 4 = 5

To Get 4

5 × 2= 10

30 – 10 = 20

20 ÷ 5 = 4

To Get 5(down)

5 × 4= 20

30 – 20 = 10

10 ÷ 2 = 5

To Get 2

5 × 4= 20

30 – 20 = 10

10 ÷ 5 = 2

Lantern Step Exercise 6b(Page 20)

8 × 4 ——>  Z = 38

8×4= 32

38-32= 6

This implies that Z  is 6

To Get 38

8×4 = 32 + 6 = 38

To Get 8

38-6=32

32 ÷ 4= 8

To Get 4

38-6=32

32 ÷ 8= 4

2nd Example

10 × 10 —–> Z= 106

To Get Z

10×10= 100

106 – 100 =6

To The first 10

106 -6= 100

100 ÷ 10 = 10

To The second 10

106 – 6= 100

100 ÷ 10 = 10

Lantern Step Exercise 8a

Using example 1

To Get 9

6×3= 18

18÷2 = 9

To Get 6

9×2= 18

18 ÷ 3= 6

To Get 3

9×2= 18

18 ÷ 6= 3

Lantern Step Exercise 8b

Using the second example

To Get 64

8² =64  or √4096 = 64

To Get 4096

64² = 4096

To Get 8

√64 = 8

Lantern Step Exercise 11a

Using Example 1

To Get 1

¾ + ¼ = 1

To Get ¼

1 – ¾ = ¼

To Get ¾

1 – ¼ = ¾

Using Example 2

To Get 5/9

⅓ + ⅔ = 5/9

To Get 1/3

5/9 – ⅔ = ⅓

To Get 2/9

5/9 – 2/9 = 3/9

By reducing to the lowest terms, you have 1/3
