Elementary school mathematics. 12 times of a number is 3 12 times more than 8 times of this number. What's this number?
3 12/( 12-8)=78
Checking calculation: 78* 12=936
78*8=624
936-624=3 12
Let the number be y, 8 times =8 y, 12 times = 12 y, with a difference of 4 y, and 4 y is the extra 3 12, that is, 4y=3 12/4. Solve the equation Y = 312.
