Answer:
the tables have a pattern of consistancy
Step-by-step explanation:
The total number of pieces of chalk in the classroom will be the number of pieces in the 4 boxes in addition to the six individual pieces.
The average box of chalk holds 12 pieces of chalk
This means that 4 boxes have 12*4 = 48 pieces
Total number of pieces = 48 + 6 = 54 pieces of chalk
300/250 = 6/5
1/5 = 20%
You are correct, well done.
