means the same thing as adding fourteen times.

means the same thing as adding eight times.

On our number line, we can make jumps of

We are splitting into equal groups, so we are dividing by .

To solve we multiply by the reciprocal.

Add the numerators and leave the denominators the same:

Answer:

First, multiply the numbers, ignoring the decimal points:

Since the two factors in the original product have three digits to the right of the decimal points between them, position the decimal point in the product such that three digits are at its right. The result, therefore, is

and , so we are looking for numbers that fall between 0.4 and 0.6 exclusive. Of the four choices, 0.44 and 0.55 fall between these numbers. The correct response is two.

In order to solve this question, we need to first recall how to find the area of a rectangle.

Substitute in the given values in the equation and solve for .

Divide both sides by

Dividing by a fraction is the same as multiplying by its inverse or reciprocal.
