Which of the following does not form a proportion? i) 15,45,40,120 ii) 33,121,9,96 iii) 33,44,75,100 iv) 4,6,8,12​

Answer 1

Answer:

it's answer ii) 33,121,9,96

Step-by-step explanation:

i) 15,45,40,120

(15×120) = 1800 and (45×40) = 1800

so, it is a proportion form.

iii) 33,44,75,100

(33×100) = 3300 and (44×75) = 3300

so, it is a form of proportion.

iv) 4,6,8,12

(4×12) = 48 and (6×8) = 48

so, it is a proportion form too.

But, ii) 33,121,9,96

(33×96) = 3168 and (121×9) = 1089

so, it's correct answer is ii) 33,121,9,96.

Answer 2

Answer:

Option ii)33,121,9,96 does not form a proportion

Step-by-step explanation:

i)15 40 ii)33 9 iii)33 75 iv)4 8

45 120. 121 96. 44 100 6 12

= 1 1 = 3 3 = 3 3 = 2 2

3 3 11 32 4 4 3 3

∴ Option 2 has different fraction than others so they does not form a proportion
