## Pre-Algebra 13 – Reciprocals and Division with Fractions

Hello. I’m Professor Von Schmohawk and welcome to Why U. In the last lecture, we saw how fractions are multiplied. When multiplying fractions, the numerators

## Ex: Solve a One Step Equation by Multiplying by Reciprocal (a/b)x=-c/d

We want to solve the equation three-fourths, x equals negative nine-eighths. Three-fourths, x means three-fourths times x, and therefore, the solution to the equation is

## Ex: Solve a One Step Equation by Multiplying by Reciprocal ax=c/d

We want to solve the equation four x equals 8/7. Four x means four times x, and therefore the solution to the equation is the

## Ex: Solve a One Step Equation by Multiplying by Reciprocal (a/b)x=c/d

We’re going to solve the equation four-ninths, x equals five-thirds. We’ll take a look at two methods for solving this equation. Four-ninths x means four-ninths

## Application: Write and Solve a One Step Equation: Height (a/b)x=c (Round)

Aiden is 39 inches tall. He is 4/7 as tall as his brother. How tall is his brother? And we’re told to round the answer

## Solve an Equation with a Rational Exponent (x+b)^(c/d)=f (Two Solutions)

We want to solve the given equation. For the first step we will clear the fractional exponent from the equation by raising both sides of

## SAT Math (Geometry) – Practice 3.6
