Answer 2

No 25, 15, 6, 5 are not in proportion

Given :

Four numbers 25, 15, 6, 5

To find :

To check whether they are in proportion

Solution :

Step 1 of 3 :

Write down the given numbers

The given numbers are 25, 15, 6, 5

Step 2 of 3 :

Write down the condition for proportion

Four given numbers a , b , c , d are said to be in proportion if product of extreme terms = product of middle terms

That is , a × d = b × c

Step 3 of 3 :

Check whether 25, 15, 6, 5 are in proportion

Extreme terms are 25 & 5

Middle terms are 15 & 6

Product of extreme terms = 25 × 5 = 125

Product of middle terms = 15 × 6 = 90

Thus we observe that

Product of extreme terms ≠ Product of middle terms

Hence we can conclude that 25, 15, 6, 5 are not in proportion
