one of the number is -
-9/8
Find the other number

​

Answer 1

Answer:

It is only the ratio to find out the actual numbers their ratios should be multiplied by a fixed number. There can be many numbers in the given ratio. For example if we multiply the ratio with 2 we get 10 and 12. 10 and 12 also in the ratio of 5:6.5:6. Now the second number is 72, so with what number should we multiply 6 to get 72? To find the number divided 72 with 6. We get 12. So our fixed number is 12. Multiply the first number with fixed number that is 5×12=60.5×12=60. So 60 is the required number.
