nuele:
I solved it this way, using letters to make a formula

Please I need help in solving this quantitative reasoning for primary 6. Abeg help your sister in need ooo

unclemaths:


Nice one. But for 6th graders, you will need a simpler method for them to understand.

NwaAmaikpe:



My people say that "mgbe onye tetere bu chi ya"
I am proud of you OP on your quest to attain knowledge.
It is better late than never.

With that said.
I wish you success in your forthcoming FSLC.

You spent more time fixing your artificial nails than learning quantitative

Anyway

6. √121 * 11 = 121 A

7. 2/√4= 1 ( no answer)

8. √169 * 9 = 117 B

9. (3/1)² = 9 E


Test 3

1. 20²-17² =111 (No answer)

2. √(40+9²) = 11 A

3. 30²-25² = 275 E

4. 8²-7²= 15

Nipeks:
A. Example




1. 111 (None of the options is correct. C is the closest).

Solution
a = 20
b = 17
x = ?
x = a² - b²
x = 20² - 17²
x = 400 - 189
x = 111


2. 11 (A).

Solution
a = ?
b = 9
x = 40
a = √(b² + x)
a = √(9² + 40)
a = √(81 + 40)
a = √121
a = 11


3. 16 (E).

Solution
a = 5
b = ?
x = 9
b = √(a² - x)
b = √(5² - 9)
b = √(25 - 9)
b = √(25 - 9)
b = √16
b = 4


4. 275 (E).

Solution
a = 30
b = 25
x = ?
x = a² - b²
x = 30² - 25²
x = 900 - 625
x = 275


5. 15 (A).

Solution
a = 8
b = 7
x = ?
x = a² - b²
x = 8² - 7²
x = 64 - 49
x = 15



B. Example




6. 121 (C).

Solution
a = 21
b = 11
x = ?
x = √a * b
x = 11 * 11
x = 121


7. 1 (None of the options is correct. D is the closest).

Solution
a = 4
b = ?
x = 2
b = x / √a
b = 2 / √4
b = 2 / 2
b = 1


8. 117 (B)

Solution
a = 169
b = 9
x = ?
x = √169 * 9
x = 13 * 9
x = 117


9. 9 (E)

Solution
a = ?
b = 1
x = 3
a = (x / b)²
a = (3 / 1)²
a = 3²
a = 9



C. Example




10.

femi4:
This approach will not satisfy the given exercise

a²-b² = c does

nakaman:
I wonder how d expect pri 6 student to know dis thing

femi4:
Aaah

frozen70:


Lol, how did you sight it

fergie001:
6. A
7. Answer is 1
8. B
9. E

1. 111
2. A
3. E
4. E
5. A

shumuel:


Oga stop complaining, you dont need this Epistle if you look at it with the eye of a kid, the Answer is there but your kmowledge of Advance Mathemathics would not allow you to see the answer, it is not called Quantitative reasoning for no reason, so always think outside the box, in this case (Forget the Examples) and look at the sums, and the answer you would find

Pearlqueen:
For question 7, the right answer is there and not just whole 1. 1/2 is the correct answer.

Translated into:
1/2*2/1 =2/2 = 1.

Ken4Christ:


You are contradicting yourself. You said the answer is 1/2 but your working reveals otherwise. Please go back and read the question well. The answer is 1

1*square root of 4 = 2

So the missing number is 1.

richyfunky:
Test 3
Samples
(10+7)*3=51
(15+12)*3=81

OneCorner:
Bring it to my place

Ladylite:


It's square root ma. The lowest number is multiplied by the square root of the number above and the answer is the number on the triangle

E.g first diagram is 4*root of 9 = 12, where root of 9 is 3

Hope it is clear

Pearlqueen:
Square root of 4=2

1/2*2 is same as 1/2*2/1 = 2/2 =1
