A full strip plus another half of staples contains 315 staples. How many staples are in half

A full strip and a half of staples = 1 strip + 0.5 strips = 1.5 strips

1.5 strips = 315 staples

Divide both sides of the equation by 1.5 to find out how many staples are in one strip:

1.5 strips : 1.5 = 315 staples : 1.5

1 strip = 210 staples

Now halve both sides of the equation to find out how many staples there are in half a strip:

1 strip : 0.5 = 210 staples : 0.5

0.5 strips = 105 staples

Therefore, there are 105 staples in half (0.5) a strip.
