Solving Word Questions
With LOTS of examples!
In Algebra we often have word questions like:
Example: Sam and Alex play tennis.
On the weekend Sam played 4 more games than Alex did, and together they played 12 games.
How many games did Alex play?
How do we solve them?
The trick is to break the solution into two parts:
Turn the English into Algebra.
Then use Algebra to solve.
Turning English into Algebra
To turn the English into Algebra it helps to:
- Read the whole thing first
- Do a sketch if possible
- Assign letters for the values
- Find or work out formulas
You should also write down what is actually being asked for, so you know where you are going and when you have arrived!
Also look for key words:
| When you see | Think | |
|---|---|---|
add, total, sum, increase, more, combined, together, plus, more than | + | |
minus, less, difference, fewer, decreased, reduced | − | |
multiplied, times, of, product, factor | × | |
divided, quotient, per, out of, ratio, percent, rate | ÷ | |
| maximize or minimize |
