Question

Which of the following ratios is not equivalent to 10:5?
a)20:10
b)2:1
c)2:5​

Answer 1

Answer:

c) 2:5 ( ratio is not equivalent to the ratio 10:5)

Step-by-step explanation:

According to the information provided in the question it is given as

Ratio = 10:5

We need to find the equivalent ratio to this options are as follows

a)20:10

b)2:1

c)2:5​

Main ratio = 10:5

                  = 10 /5  Converting to the lowest term

                  = 2 / 1 = 2:1

                 =( 10:5 = 2:1)

a) Ratio = 20:10

Solving the ratio

20 /10

Converting to the lowest term we get

2 / 1   (As both are divisible by 10)

Hence 20 /10 = 2 /1

Or we can say that (20:10 = 2:1)

Now

b)Ratio 2 : 1=  2/1

          ( 2:1 = 2:1)

c) 2:5

Converting to lowest term

 2 /5  can not be reduced further

Hence,

2:5 is not equivalent to 10:5

  Hence option (c) is not equivalent to 10:5
