Even with easy questions, set them out properly
so that you are in good habits for the harder ones.
Alan and Bob have 28
smarties.
If they share them in the ratio 1:3
how many sweets does Alan
get?
Start by setting out the
question in a ratio form:
Now write the number of portions next to the ratio:
Next, put the number of
smarties below the portions:
Work out how to turn portions
into smarties,
[times by seven] and do the same to the ratio:
| Alan |
: |
Bob |
|
| 1 |
: |
3 |
4 |
| 7 |
: |
21 |
28 |
Finally, answer the question!
Alan gets 7 sweets.
