Question

13. If m:n = 5:2 and n:o = 8:10, then m:o is :
O 9:2
042
0 2:9
O 2:1​

Answer 1

Answer:

The correct answer is option to the question D)n:o = 2:1.

Step-by-step explanation:

A ratio m:n can also be written as m/n too.

So from the given data in the question the ratio m:n = 5/2 = m/n

And similarly the ratio n:o = 8/10 = n/o

By multiplying m/n by the ratio n/o we get m/o as the n in the denominator and numerator gets cancelled out.

So by multiplying the values of m/n and n/o= m×n/n×o = 5×8/10×2 = 40/20 = 4/2= 2/1

So we can conclude that n/o=2/1

The ratio n:o=2:1

Option D)n:o=2:1 is the correct answer to the question.

Answer 2

Answer:

The ratio of m:o = 2:1

Step-by-step explanation:

Here in the question, we have given the ratio of

m:n=5:2........(1)

n:o=8:10.........(2)

so, According to the question,

now making the value of n the same in both the equations, as "n" is the common term in both the ratios,

so we have to multiply equation (1) by 4, and we get

m:n= 20: 8........(3)

and note down the second equation as it is,

n:o=8:10............(2)

from equations (2) and (3) we get,

the ratio of m:n:o= 20:8:10

as we have to find the ratio of m:o= 20:10

now reducing the numerator and denominator ratio we get,

m:n=2:1

Therefore, m:o=2:1

Hence, option 4 is the correct answer.
