cert 22.2 U To 3. Draw an area diagram to find (0.36) (0.53). Label and organize your work so that it can be followed by others.
Masteriza [31]

The result of the product of (0.36) and (0.53) is 0.1908

<h3>How to determine the product</h3>

The product expression is given as:

(0.36) * (0.53)

Rewrite the product as follows:

(0.36) * (0.53) = (0.3 + 0.06) * (0.5 + 0.03)

Expand the product

(0.36) * (0.53) = 0.3 * (0.5 + 0.03)+ 0.06 * (0.5 + 0.03)

Expand

(0.36) * (0.53) = 0.15 + 0.009+ 0.03+ 0.0018

Evaluate the sum

(0.36) * (0.53) = 0.1908

See attachment for the area diagram of the product
