Question 4 of 5Which two ratios represent quantities that are proportional?1419A. , andB. 31 and 2C.40and36 46D.40and10048120SUBM

Answer 1

Given,

`(4)/(9)\text{ and }(14)/(19)`

It is the simplest form.

So, option a is not proportional.

b)

`(27)/(81)=(21)/(72)`

The simplest form of the expression is,

`(3)/(9)=(7)/(24)`

The simplest form is not equal

So, option b is not proportional.

c)

`(30)/(36)=(40)/(46)`

The simplest form of the expression is,

`(5)/(6)=(20)/(23)`

The simplest form is not equal

So, option c is not proportional.

d)

`(40)/(48)=(100)/(120)`

The simplest form of the expression is,

`(20)/(24)=(20)/(24)`

The simplest form is equal

So, option d is proportional.

Hence, the correct option is (d).
