A week = 7 days.
A fortnight = 14 days.
Another hint

Back to Questions

4 + 5 + 11 = the amount you must subtract from the total number of marbles she started with.
Another Hint

Back to Questions

First you must add up the days Brian has lost. You then subtract this answer from the total number of days he started with.
Another Hint

Back to Questions

3 days + a week = 3 + 7 = 10 days LOST.

Another Hint

Back to Questions

14 (a fortnight) - 10 = answer

Christmas is on the 25th of December. There are 31 days in November.
Another hint

Back to Questions

There are a few ways to do this, but here's one.
Add up the total number of days in November (31) and the number of days in December until Christmas (25).

This means an equation like this: 31 + 25 = 56

Now you subtract the starting date (9th) from this total.
Back to Questions

First, you need to add up what George has used (spent and saved).
Another Hint

Back to Questions

6km - 2.5km = answer.
Back to Questions

$5.50 + $2.50 + $12.00 = the amount you must subtract from $25.00
