A stack of thirty cards is placed next to a ruler, and the height of stack is measured to be 3 /4 of an inch. How thick is one card?

You need to divide 3/4 inches by 30 cards.

Using the reciprocal rule,

(3/4)/30 = (3/4)*(1/30)

Multiplying fractions,
(3/4)*(1/30) = 3/120 = 1/40 inches.

The thickness of the one card will be 1/40 inches.

What exactly is division?

The term "division" refers to the separating of something into multiple portions and the sharing of something among several individuals, locations, and other entities.

The height of stack = 3 /4 of an inch

Let the thickness of the one card will be x;

[tex]\rm x= \frac{\frac{3}{4}}{30} \\\\ x= \frac{3}{4} \times \frac{1}{30} \\\\ x= \frac{1}{40} \ inches[/tex]

Hence,the thickness of the one card will be 1/40 inches.
