Step-by-step 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:

[tex]19+0.125[/tex]

Express the decimal part as a fraction

[tex]\displaystyle 0.125=\frac{125}{1000}[/tex]

Simplify the fraction by 125

[tex]\displaystyle 0.125=\frac{1}{8}[/tex]

Now we combine both parts to produce the mixed number

[tex]\displaystyle 19.125=19\ \frac{1}{8}[/tex]

(35)

The net change from Tuesday to Wednesday is

[tex]19.125-18.75=0.375[/tex]

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

[tex]\displaystyle 0.375=\frac{375}{1000}[/tex]

And as before, we simplify by 125 to get

[tex]\boxed{\displaystyle 0.375=\frac{3}{8}}[/tex]
