My answer is 400 if you still need it. the way I did it is by adding 250 and 157 and then dividing it by 25 which is 16.8 then 25 times 16 and it's 400 and to get to 420 it's 20 books so 20 books are on the table. Hope this helps

first flip the second fraction so you cross multiply

now it's 225/60
you can simplify it so its 15/4 as improper fraction or 3 3/4 as proper fraction
