Question

The sum of two natural numbers is 128.Which of the following cannot be the ratio of these two numbers?
a) 7:9
b) 7:1
c) 41:23
d) 32:1

Answer 1

32 : 1 is not the correct ratio for given statement

Because,

If we add any two no. Given in ratio tand then decide 128 by the sum

Then we get,

7 : 9 = 7 + 9 = 16

128 / 16 = 8

7 : 1 = 7 + 1 = 8

128 / 8 = 16

41 : 23 = 41 + 23 = 64

128 / 64 = 2

But we don't get a perfect no. In the situation 32 : 1
