tiles problem

Post by equation »

This has got me confused. Year 7 question. I might be looking too much into it.
A couple are moving into their new home. They would like to have their bathroom floor tiled. The bathroom is rectangle shaped and has sides 4.6m by 6m. What's the side of the biggest square shaped tile in cms that could be used so that no space is left without tiles? He can't cut the tiles by the way.
Thanks.

Turn the side length into centimetres and think about factors ... don't want to give the answer just a hint.

See if you can solve it now. :D

Think a bit bigger - in terms of factors, look at the shorter side first...

Convert to cms
4.6m = 460cm and
6m = 600cm.

Multiply to get 460600.

Then calculate HCF of 460600 which is 20cm

It is very standard Year 7 homework and I guess not relevant for 11+

Why are you multiplying the dimensions? It is not necessary ... just find HCF of the two sides.

You cannot find a HCF of one number!
