just critical reasoning

the square root of 9 = 3

then multiply it by 4

Answer = 12

that is how the example is solved

very simple

in the second example,

the square root of 36 = 6

then multiply it by 5

Answer = 30



in the third example,

the square root of 64 = 8

then multiply it by 2

Answer = 16

Well done

You should join us on https://www.algebra.com/

Fun times

adewumiopeyemi:
It is a pity That some graduate can not solve this primary 6 equation I weep for Nigeria graduate

how do u know she is a graduate?

Prec1ous:
First Diagram

1. Square root of 9 = 3
2. 3 * 4 = 12

Second Diagram

1.Square of 10 = 100
2. Square of 7 = 49
4. 100 - 49 = 51

This is what you need @OP

Good job man.

Odopatience22:
Please I need help in solving this quantitative reasoning for primary 6. Abeg help your sister in need ooo

it simple

from the example its
12 / 4 = 3
3 x 3 = 9


30/5 = 6
6x6= 36

16/2=8
8x8=64

there u have the formulae solve the rest

Very easy.

tomdon:
Na primary school work people they get muscle show their self

Lol.. Any pupil who gets this correctly will be very bright .. Questions like this are still asked in GMAT

Odopatience22:

Who is your sister

Lantern would just be disgracing adults from time immemorial.

Let me give you a secret, go and buy the teacher's guide. You will just show up like a pro that knows it all

femi4:
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

You just had to?

Not everyone can reason mathematically and if you can, be happy for the gift. Don't be insensitive.

Hhh

Olodo,i no it but i wont tell u

Wow

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

Oil de ur head.... Correct

You must be married with 4 kids by now

Ihutomi:
For we that finished primary sch in the Kate 90s we don't know what u are talking abt ,so good luck.

tomdon:
Haba, so primary school girls have made it to nairaland now. Nairaland is finished

The OP is a mother or guardian seeking help for her child's homework .Look closely you will see her pink artificial nails .

Ladylite:

A beauty and brain is the real slay queen.

LINTUNE:
lol for pry 6 assignment?

Lolz..

I came late

Hmmm

My skills in quantitative reasoning was decent back then in the 90s. Seriously it took me a while to grasp presently.

Funny enough some job interviews bring this back.

Already Answered
But too cheap

Shibaraba:
Plenty viewers no answer.... Lwkmd. Na to boast I will feed your family, I can buy your generation them sabi. Olodocious fellows.

Shibaraba know book.
Upper triangle na perfect square. Multiply by number below gives the number at the apex of the triangle. Simple
thus these are your answers

6=121
7=1....as no one no answer
8=117
9=9



Second one. The two right numbers added together multiplied by 3 will give you the answer on the right. MI o le wa ku

An imaginary 3 you mean?

Do you know why it works?

1. 12 / 4 = 3
Square of 3 = 3 * 3 = 9


2. 30 / 5 = 6
Square of 6 = 6 * 6 = 36


3. 16 / 2 = 8
Square of 8 = 8 * 8 = 64

For the first picture following example B:
Answers...
6=A
7=B
8=B
9=E

B: Example: Diagrams 1: √9 × 4 = 3×4 = 12
2: √36 × 5 = 6×5 = 30
3: √64 × 2 = 8×2 = 16

No 6: √121 × 11 = 11×11=121.
No 7: √4 × [ ] = 2
2 × [. ] = 2
Ans: [. ] = 1. No answer in the options.
No 8: √169 × 9 = 13×9=117.
No 9: √[. ] × 1 = 3
√9 × 1 = 3
3 × 1 = 3. Ans: [. ] = 9.
