I'm not exactly sure but you have to find out how much pages are on 1 page by dividing 90'000 by 325, which gets you 276. Then you times 81 by 276 to find out how much words jamie read, which gets you 22,356. then you will divide it by 120, which is 2 hours which gets you 186.
What you do is multiply regularly then add the negative sign, but if your multiplying 2 negatives it’s a positive answer. I cant help with the Fractions caz I’m not good at them lol .
