David has 50 cards numbered from 1 to 50.
David puts a red sticker on every card that has a multiple of 6 on it and a blue sticker on every card that has a multiple of 8 on it.
Some cards will have both a blue sticker and a red sticker on them.
What numbers will be on these cards?
Answer:
The numbers that are a multiple of 6 are 6, 12, 18, 24, 30, 36, 42, 48
The numbers that are a multiple of 8 are 8, 16, 24, 32, 40, 48
Therefore, the numbers with both coloured stickers are 24 and 48
