Divide 22.8 by the sum of a number and 0.5, and the quotient is 12


Let this number be X
12(x+0.5)=22.8
12x+6=22.8
12x=16.8
x=1.4
A: the number is 1.4



The difference of 3 / 5 divided by a number minus 1 / 6. The quotient is 3 / 4. Find this number (by solving the equation)
In a hurry


(3/5)/(X- 1/6)=3/4
X- 1/6=4/5
X=4/5 +1/6
X=29/30
