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 divided by that number.
The
Property of Reciprocals states that any non-zero number multiplied
by its reciprocal yields a product of one. |
