Question

Middle terms of 30:40::45:60 are
(30 and 60,40 and 45,45 and 60)

Answer 1

Answer:

Answer

Four numbers a,b,c,d are said to be in proportion, if a:b=c:d we write a:b::c:d

Let,

a=30,b=40,c=45,d=60

Then,

Product of extremes =(30×60)=1800

Product of means =(40×45)=1800

∴ Product of extremes = product of means

Hence, 30,40,45,60 are in proportion
