Why do you find the reciprocal of fractions when dividing?
Most people find multiplication by a fraction easier than dividing by a fraction. Dividing by a fraction is equivalent to multiplying by its reciprocal. For example, 10 / (3/4) would require you to divide by 3/4. How many three-quarters in ten? Hmmm... Not that easy. Instead, try multiplying by 4/3 Much easier: 10*(4/3) = 40/3 = 13.33...

What is the slope of a line that is perpendicular to the line represented by the equation 3x plus 4y equals 12?
4/3 First, get this into slope-intercept form (get y by itself). 3x+4y=12 -> Move 3x to the right by subtracting from both sides. -3x -3x 4y=12-3x -> get y alone by dividing everything by 4. 4y=-3x+12 ÷4 ÷4 ÷4 y=(-3/4)x+3 -> The slope is -3/4. To get the perpendicular line's slope you take the slope (-3/4) and flip it and switch the sign: negative becomes positive, 3/4 becomes 4/3.
