greatest commom dinaminator of 40 and 64 is 8 so,
divide each number by 8
40 divided by 8 =5
64 divided by 8 =8
Or you can do bc it gives you the 5 and the numerator you do 40 divided by 5 and get 8 so that means to get the second fraction you are divided the first one by 8 thats why 40 divided by 8 is 5 and youre going to do 64 divided by 8 which is 8. put the two numbers together and you get 5/8! :)
