PLEASE SHOW YOUR WORKING OUT THANKS

There are 64 cards in a pack. Each card is either red or black. The ratio of the number of red cards to the number of black cards is 1: 1 8 red cards are removed from the pack. Find the ratio of the number of red cards now in the pack to the number of black cards now in the pack. Give your answer in its simplest form.

Answer 1

This ratio would be 24:32!
Hope it helps!

Answer 2

So the ratio 1:1 means that there are 32 cards of each colour (1 + 1 = 2, 64 ÷ 2 = 32). If we remove 8 red cards, there are then 24 red cards, and still 32 black cards. This ratio would be 24:32, which you can simplify to 12:16, then 6:8, and then 3:4, which is the final answer. I hope this helps!
