Question

Rachel can read 13 pages of a book in 4/5 of an hour. How many pages can she read in 4 hours?

Answer 1

Answer:

my answer is 17 5/5

Step-by-step explanation: so what i did was that i add 13 and 4/5 but i can't add like that so i put 13/1 + 4/5 and they don't have the same denominator so i did 1 x 5 so if i do it on the bottom i have to do it on the top and so i did 13 x 5 and 13 x 5 is 65 and 1 x 5 is 5 and so my new fractions are 65/5 + 4/5  and i add both them and got 69/5 so i divided 69 and 5 and got 13 4/5 and then i add 69/5 plus 4 and turn the 4 into 4/1 and multiply 1 x 5 and have to do it on the top so 4 x 5 and got 20/5 and now add 69/5 + 20/5 and got 89/5 as my answer and divided 89 divided by 5 and got 17 5/5 and know it that is my answer.

hope it helps you!
