Irene is going to read a 216-page book. if she reads at a rate of 18 pages per day, how many days will it take her to read 1313 of the book?

1313 pages in total / 18 pages per day = 72.94 days

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Yea they are simplyfiy the ratios
