Question

Loni has read 25% of a book if she has been reading for 5 hours, how many more hours will it take her to complete the book

Answer 1

Answer:

15 hours

Step-by-step explanation:

The way we can find this is by taking both 25% and 5 and multiplying them by 4. The reason we do this is because 25% x 4 will equal 100% so it will show us how many hours total she needs to read.

5 x 4 = 20

Now we just subtract the amount of hours she has already read for which is 5.

20 - 5 = 15

Hope this helped ! !

Answer 2

Answer: It will take her 15 more hours to finish the book.

Step-by-step explanation:

25% : 5h

50% : 10h

75% : 15h

100% : 20h

It would take 20 hours to complete the book, but because she already read for 5 hours, it would be 15 to finish the book.
