Since Tracy can jump rope 26 times in a minute, we can make a equation.

  • [tex]1\:minute=60\:seconds[/tex]

Now here is our equation

[tex]\frac{26}{60} =\frac{x}{90}[/tex]

cross-multiply

[tex]60x=2340[/tex]

do simple algebra and divide

[tex]x=39[/tex]

Tracy can jump rope 39 times in 90 seconds.
