Question

solve the proportion 3/8 = 11/x . Please help me very quickly i don't kno what to do here so i need help.

Answer 1

`(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 2

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
