Question

find where 11,22,2,4 are in proportion​

Answer 1

Step-by-step explanation:

Product of extreme = 11 x 4 = 44

Product of means = 22 x 3 = 44

44=44

They are in proportion

Answer 2

Required Answer:-

Question ?

• Find whether 11,22,2 and 4 are in proportion are not.

Solution:

We know that if two ratios are in proportion, then,

→ Product of extremes = Product of mean. i.e.,

If the numbers are a, b, c and d, then,

→ a : b : : c : d if and only if ad = bc.

So, 11,22,2 and 4 are in proportion, then 11 × 4 must be equal to 22 × 2

11 × 4

= 44 and,

22 × 2

= 44

So,

→ 44 = 44

→ Therefore, the given numbers are in proportion.
