Question

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?

Answer 1

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.
