Question

The value of a stock increased 1 ¼ points Monday morning. On Monday afternoon, the value of the stock decreased 1 ⅔ points. On Tuesday morning, the value increased 1 ½ points. What is the overall change in the stock’s value?

Answer 1

`Change = 1(1)/(12)`

Explanation:

Given

`Increment = 1(1)/(4)`

`Decrement = 1(2)/(3)`

`Increment = 1(1)/(2)`

Required

Determine the overall change

The overall change is calculated by adding all increments and subtract the decrement.

This is done as follows;

`Change = 1(1)/(4) - 1(2)/(3) + 1(1)/(2)`

Convert to Improper Fraction

`Change = (5)/(4) - (5)/(3) + (3)/(2)`

Take LCM

`Change = (15 - 20 + 18)/(12)`

`Change = (13)/(12)`

Convert to mixed number

`Change = 1(1)/(12)`

Hence; the overall change is an increment of
`1(1)/(12)`
