Alex777 [14]

Answer:

3/3 or just 3.

Solve for points....

Answer:

Step-by-step explanation:

For Mr Rowley,

Ratio of Number of home works to the number of exit tickets = \frac{12}{14}

                                                                                                      = \frac{6}{7}

                                                                                                      = 6:7

For Ms Rivera,

Ratio of Number of home works to the number of exit tickets = \frac{36}{42}

                                                                                                      = \frac{6}{7}

                                                                                                      = 6:7

Since, both the ratios are same, fractions will be proportional.

\frac{12}{14}=\frac{36}{42}
