The Boisson Vineyard in Burgundy
is one of the vineyards which has decided to test the effect
of the bacteria on the growth of their grapevines.
A technician at the vineyard adds 1/25
of the box to a vine. How many units of the bacteria is added
to the vine?
To answer this question
we can multiply the contents of the box (25 units) by the
amount used (1/25
of the box). 25 × 1/25 = 1. 25 and
1/25 are known as multiplicative inverses or reciprocals,
because when multiplied, the result is one.
The reciprocal of any number is just one didvided
by that number.
The Property of Reciprocals states
that any nonzero number multiplied by its reciprocal yields a
product of one.
