Did you figure it out?

Solution:  The number of candles in the boxes will be four numbers whose average is 450 ÷ 4 = 112.5. Since the numbers are each one apart, we can reason that they are the two whole numbers before and after 112.5. So, there are 111, 112, 113, and 114 candles in the boxes. The full box therefore has 114 candles.

 

 

 

 

 

 

 

 

Did you figure it out?

Solution:  Since an inch is 2.54 centimeters, that means that 70 inches is 70 × 2.54 = 177.8 centimeters. The white cord is 180 centimeters long, which is 180 – 177.8 = 2.2 centimeters longer.
