Answer 1

Answer:

$\boxed{x=\dfrac{121}{2}\to x=60.5}$

Step-by-step explanation:

$\dfrac{3}{6}=\dfrac{x}{121}\qquad\text{simplify}\ \dfrac{3}{6}=\dfrac{3:3}{6:3}=\dfrac{1}{2}\\\\\dfrac{1}{2}=\dfrac{x}{121}\qquad\text{cross multiply}\\\\2x=121\qquad\text{divide both sides by 2}\\\\x=\dfrac{121}{2}$

Answer 2

Answer:

60.5 =x

Step-by-step 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
