I could be wrong, but if the number is x, then my best guesstimate would be...
x(2/3)10=x(1/4)
Solve for x either as a fraction or a decimal.
Divide by x on both sides...
(2/3)(10/x)=(1/4)
(10/x)=(1/4)(2/3)
(10/x)=0.4167
Divide both sides by 10...
(1/x)=0.04167
Take the inverse of both sides...
x=(1/0.04167)
x=24
Check your answer by substituting 24 for x in the original equation...
24(2/3)10=24(1/4)
(8)(2)10=(6)(1)
1610=6, or...
6=6, TRUE
Therefore, x=24.
Make sense?
