Kisachek [45]

The ratio of of number of homework papers to number of exit tickets of Mr Rowley and Ms. Alvera are not equivalent.

<h3>Ratio</h3>

A ratio is a number representing a comparison between two named things. It is also the relative magnitudes of two quantities usually expressed as a quotient.

Mr Rowley:

  • Homework papers = 16
  • Tickets to return = 2

Ratio of number of homework papers to number of exit tickets = 16 : 2

= 16 / 2

= 8 / 1

= 8 : 1

Ms Alvera:

  • Homework papers = 64
  • Tickets to return = 60

Ratio of number of homework papers to number of exit tickets = 64 : 60

= 64/60

= 16 / 15

= 16 : 15

Therefore, the ratio of of number of homework papers to number of exit tickets of Mr Rowley and Ms. Alvera are not equivalent.

Why is it important to be able to solve for variables in equations?
stellarik [79]
Solving for variables in equations is important for many reasons.  Of course, it's important to be able to solve for them so you can pass math tests.  But even more so, it's important for real-life applications.  There are many uses for solving equations.  They can provide answers for mathematicians, accountants, insurance companies- you name it!  There are way too many to list!  It may not seem important now, but just keep working at it!  I personally think solving equations is a ton of fun!
