Answer 1

Answer:

$Wednesday = \frac{1}{2}$

Step-by-step explanation:

Given

$Monday = \frac{1}{4}$

$Tuesday = \frac{1}{4}$

$Wednesday = Others$

Required

Determine the fraction of Wednesday

The summation of fractions on each day must be equal to 1.

So:

$Monday + Tuesday + Wednesday = 1$

Substitute values for Monday and Tuesday

$\frac{1}{4} +\frac{1}{4} +Wednesday = 1$

Collect Like Terms

$Wednesday = 1 - \frac{1}{4} -\frac{1}{4}$

Take LCM

$Wednesday = \frac{4 - 1 - 1}{4}$

$Wednesday = \frac{4 - 2}{4}$

$Wednesday = \frac{2}{4}$

Simplify fraction

$Wednesday = \frac{1}{2}$
