Three seventh of a number is 15 find the number

Answer 1

Let's start by setting up an equation to represent the problem.

Let x be the number we're trying to find.

Then, "Three seventh of a number is 15" can be translated to:

(3/7)x = 15

To solve for x, we need to isolate it on one side of the equation. We can do this by multiplying both sides by the reciprocal of 3/7, which is 7/3:

(3/7)x * (7/3) = 15 * (7/3)

Simplifying:

x = 105/3

x = 35

Therefore, the number we're looking for is 35.
