200/800 simplified would be 1/4 because 200 goes into the top number once and the bottom number four times so it's 1/4.
200÷200=1
800÷200=4
356/700 simplified would be 89/175 because you have to find the highest number that goes into both of them evenly and 4 is the highest number that goes into them evenly.
356÷4=89
700÷4=175
