Question

find the 'p' if 6,21, p,7, are in proportion.​

Answer 1

Answer:

p = 2

Step-by-step explanation:

6:21::p:7

6/21 = p/7

7 * 6 = 21p

42 = 21p

p = 2

Answer 2

6 and 7 are extremes

21 and p are means

product of extremes is 42

product of means  is also 42 ( because there are in proportion)

p = 42 divided by 12

so, p = 2
