Answer:


(88)/(3) or 29.33

Explanation:


(3)/(8)=(11)/(x)

If you think of this as a cross, you have (3 and x) and (11 and 8)

Take the 2 numbers that form a cross and don't have the variable and multiply them. After that, divide by the number with the variable.


x=(11*8)/(3) \\x=(88)/(3)\\

Answer:88/3

Explanation:

3/8=11/x

Cross multiply

3 x x=11 x 8

3x=88

Divide both sides by 3

3x/3=88/3

x=88/3
