Question

1/2 1/4 1/7 1/14 are in proportion or not

Answer 1

by using
product of extremes=product of means
1/2 ×1/14 = 1/4×1/7
1/2×14 =1/4×7
1/28=1/28
so they are in proportion

Answer 2

if 1/2 , 1/4 , 1/7 and 1/14 are in propertion then

Product of extreme terms = product of interior terms,


then

1/2 × 1/14 = 1/4 × 1/7,

1/28 = 1/28,

therefore

the given numbers are in proportion
