Question

Two numbers are in the ratio 5 :7 , if the sum of the number is 180. Fnd the smaller number

Answer 1

Answer:

75

Step-by-step explanation:

Since 5:7 is a ratio which essentially represents numbers that are of a bigger value, we can say that the two numbers can be denoted as 5n and 7n, where n is a variable that we will find from the given information. Therefore, the smaller number is 75.

Answer 2

Answer:

5 or 75 is the smallest number.

Step-by-step explanation:

let the numbers be 5x and 7x.

So, the sum of numbers = 180

Or. 5x + 7x = 180

12x. = 180

x = 180\12

x = 15

if the value of x is 15 then,

5x = 5*15 = 75

7x = 7*15 = 105.
