ioda

Answer:

$Day\ 3 = 1\frac{3}{12}$

Step-by-step explanation:

Given

$Total = 2ft$

$Day\ 1 = \frac{1}{6}$

$Day\ 2 = \frac{7}{12}$

Required

Determine the amount of snow on day 3

This can be calculated using:

$Day\ 1 + Day\ 2 + Day\ 3 = Total$

Substitute values for the known parameters

$\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2$

Collect Like Terms

$Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}$

Take LCM

$Day\ 3 = \frac{24 - 2 - 7}{12}$

$Day\ 3 = \frac{15}{12}$

Express as mixed number

$Day\ 3 = 1\frac{3}{12}$
