Question

Ella stacks two boards under a table to make it level. One board is 7/8 inch thick. The other board is 5/12 inch thick. Which equation most closely estimates the thickness of the two boards?

Answer 1

The equation that most closely estimates the thickness of the two boards is $B = \frac 78 + \frac 5{12}$

How to determine the thickness of the two boards?

The thickness of the boards are given as:

$B1 = \frac 78$ inch

$B2 = \frac 5{12}$ inch

The thickness (B) of the two boards is calculated by adding the individual thickness of both boards.

So, we have:

$B = B1 + B2$

This gives

$B = \frac 78 + \frac 5{12}$

Hence, the equation that most closely estimates the thickness of the two boards is $B = \frac 78 + \frac 5{12}$
