1. ## Grade 9 Math Help

Missed today's class due to being stuck sick in bed. I have a quiz tomorrow on Consecutive Integer Problems using fractions in the word problems. Can you help me with the following question? The larger of two consecutive odd integers is 4 less than 1/3 the smaller. Find the numbers.
Thanks

Two consecutive odd integers always take the form $2k+1,\ 2k+3$ for some integer $k$.

You are told that

$2k+3=\frac{(2k+1)}{3} - 4$

Which you now solve for $k$, and hence for the two numbers (don't be supprised if one or both are negative)

Suppose that the smaller odd integer is $n$; then the next larger one will be $(n+2)$.

So: $(n+2)$ is $4$ less than $\frac{1}{3}$ of $n$.

In other words: $n+2 = \frac{1}{3}n - 4$

Add $4$ to both sides; multiply both sides by $3$; then ...?

Can you solve it now? (The answer is a negative odd integer.)
