Answer:

7 words per minute

Step-by-step explanation:

1. To find the unit rate (words per minutes), let's set up two ratios:

  • 63:9 = x:1 or 63/9 = x/1

2. Now, let's solve for x to find how many words she can type per minute.

Step 1: Cross-multiply.

  • [tex]9 * x = 63 * 1[/tex]
  • [tex]9x = 63[/tex]

Step 2: Divide both sides by 9.

  • [tex]\frac{9x}{9} = \frac{63}{9}[/tex]
  • [tex]x = 7[/tex]  

Therefore, Christine can type 7 words per minute.
