`\displaystyle 0.375=(3)/(8)`

Explanation:

Fractions

(34)

A share of stock was worth $19.125 on Wednesday. We need to express that number as a mixed number. The approach will be:

Separate the integer part from the decimal part:

`19+0.125`

Express the decimal part as a fraction

`\displaystyle 0.125=(125)/(1000)`

Simplify the fraction by 125

`\displaystyle 0.125=(1)/(8)`

Now we combine both parts to produce the mixed number

`\displaystyle 19.125=19\ (1)/(8)`

(35)

The net change from Tuesday to Wednesday is

`19.125-18.75=0.375`

We proceed as did before to express this number as a fraction

`\displaystyle 0.375=(375)/(1000)`

And as before, we simplify by 125 to get

`\boxed{\displaystyle 0.375=(3)/(8)}`
