Build each rational expression into an equivalent rational
expression with the indicated denominator

(-7yt)/(3x) =(?)/(18xyt)

• algebra -

Start by dividing 18xyt by 3x to find the necessary multiplication to reach the new denominator.

18xyt / 3x = 6yt
Now multiply (-7yt)/(3x) by (6yt)/(6yt)

= (-42y^2t^2)/(18xyt)
