3/4
HintFind the highest common factor of both numbers and cancel it in one go, or cancel in stages.
The why36 and 48 share a highest common factor of 12, so dividing both by 12 gives 3/4. Cancelling in stages (÷2, ÷2, ÷3) reaches the same place — keep going until top and bottom share no factor except 1.
