George read 15 pages in a book in 12 minutes. at this rate, how long will it take him to finish the book if it has 85 pages?

Step-by-step explanation:

Set up a ratio in the form of pages/minute:

then fill in next to that how many pages per minute George can read:

Now we want to figure out how long (time is our unknown, so we call that x) it will take him to read 85 pages.  The 85 goes in a ratio on the same line as the other number of pages:

Cross multiply to get 15x = 1020

Now divide both sides by 15 to get x = 68 minutes, which is an hour and 8 minutes.

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
