Question

Solve for the variable 3/6 = x/121

Answer 1

`\boxed{x=(121)/(2)\to x=60.5}`

Explanation:

`(3)/(6)=(x)/(121)\qquad\text{simplify}\ (3)/(6)=(3:3)/(6:3)=(1)/(2)\\\\(1)/(2)=(x)/(121)\qquad\text{cross multiply}\\\\2x=121\qquad\text{divide both sides by 2}\\\\x=(121)/(2)`

Answer 2

60.5 =x

Explanation:

3/6 = x/121

We can use cross products

3*121 = 6*x

363 = 6x

Divide by 6

363/6 = 6x/6

60.5 =x
