To solve proportion problems in Year 7 Math, follow these simple steps:
Find the Ratio: First, look for the two amounts you need to compare. For example, if there are 4 apples for every 6 oranges, the ratio is 4 to 6, which can be written as (4:6).
Set Up the Proportion: Next, write the proportion using the ratio you found. In our example, you can write it as (\frac{4}{6} = \frac{x}{y}). Here, (x) and (y) are the quantities we don’t know yet.
Cross-Multiply: Now, use cross-multiplication to turn it into an equation: (4y = 6x).
Solve for the Unknown: Rearrange the equation to find the unknown value. For example, you can divide both sides by 4 to solve for (y): (y = \frac{6x}{4} = \frac{3x}{2}).
Check Your Answer: Lastly, plug the value you calculated back into the original ratio to make sure it’s correct.
That’s it! Just follow these steps, and you’ll be able to solve proportion problems easily.
