Answer:
The cost for 2 more glass panes is $4.70
Step-by-step explanation:
1. Fist divide 11.75 by 5 to find out how much one pane costs, you should get 2.35.
2. Next multiply 2.35 by 2 to find out how much it is for 2 more glass panes.
Then you will get our answer ($4.70)
Cost of single pane = 11.75 / 5 = $2.35
Cost of 2 extra panes = 2*2.35 =$4. 7

A. 31/100
Change 3/10 to hundreds:
3/10 × 10/10 = 30/100
The denominator (the bottom number) must be 100.
61 - 30 is 31.
The missing number is 31/100. See image.
