If 40% of a number is equal to two -third of another number, what is the ratio of first number to the second number ? Correct Answer 5:3

Let one number be a and the other be b. From the problem statement, we can write that 40% of a = 2/3 of b Solving gives us 0.4a = 2b/3 Further simplifying to get the value of a, gives us a = 5b/3 Now ratio of the two numbers is given by a/b = (5b/3)/b = 5/3. will be your answer.
