Genevieve is an architect and has just finished the plans for a new library. She built a scale model to take to a planning meeting. The City Council members love her design so much that they have asked her for two new models.

Help Genevieve decide how she will calculate the measurements of each new model to satisfy each of the given conditions. 

The council wants a model much smaller than Genevieve’s original model to fit in a scale model of the entire city. Genevieve could multiply each length by ____

(Choose all that apply)

Billy and Ken, the school’s cross-country stars, were each running at cross-country practice. Billy was going to run ¾  of the training course, and Ken was going to run ½ of the course. However, during practice it started raining, so they could not finish their runs. Billy had finished ⅓ of his run, while Ken had finished ½  of his run.

Billy ran a total of ​ (a)   of the course. Ken ran a total of ​ (b)   of the course. This means that ​ (c)   .

• they both ran the same amount
• Ken ran more of the course than Billy
• Billy ran more of the course than Ken
