Hey there!
5/x = 30/54
FIRST: CROSS MULTIPLY the EQUATION
5 * 54 = x * 30
5 * 54 = 30 * x
270 = 30x
30x = 270
SECOND: DIVIDE 30 to BOTH SIDES
30x/30 = 270/30
CANCEL out: 30/30 because it give you 1
KEEP: 270/30 because it help solve for the x-value
NEW EQUATION: x = 270/30
THIRD: SIMPLIFY IT!
x = 9
Therefore, your answer is: x = 9
Good luck on your assignment & enjoy your day!
