How would you find the number, 3/7 of which is equal to t? (let's say it was any number, just need the equation)
ohaa [14]
Let the number be x
(3/7) x = t
I can't think of anything useful to add to this. How about an example?

Let x = 49

(3/7) x = t
(3/7) * 49 = t seven will go into 49
3 * 49 = t
t = 147
