of the total number of pages in a book, 62% have pictures and the rest have no pictures. There are 310 pages with pictures in the book. What is the total number of pages in the book?

Answers

I'm pretty sure that you need to use proportions, its simple. First, place 310 over x like a fraction. then, write an equal sign and write 62% over 100 because percentage always goes on the top of 100`s. next, on the bottom write 62x over 62 and an = sign 310,000 over 62 since you multiplied 310 with 100. for example, its cross multiply. 62 goes with x and you multiply 310 with 100. so 310,000 divided by 62 = 500 pages in total.
