We need to find how long did Steve ran than walk. In basic terms, we subtract.
The hour he ran than walk.
Subtraction.
To subtract fractions, we first have to find their LCD.
[tex] \frac{7}{8} = \frac{7}{8} \: \: \: \: \: \: \: \: \: \: \frac{3}{4} = \frac{6}{8} [/tex]
We left ⅞ be, because their LCD is 8. Now that we found our LCD, let's begin subtracting.
[tex] \frac{7}{8} - \frac{6}{8} = \frac{1}{8} [/tex]
For subtracting the current fractions, subtract the numerators and copy the denominators.
So our answer is ⅛.
Steve ran ⅛ longer than walking.
