Someone is reading a book that is 347 pages he or she is on page what is the percent of the number does this person has to read left?

33.Someone is reading a book that is 347 pages long. But he or she is already on page 203.Now, let’s find the percentage rate of the remaining number of pages. => 347 pages = 100% => 203 is the pages that he or she already read. Solve: => 347 – 203 = 144 pages left. Now, let’s find the percentage of 144 pages out of 347 pages => 144 / 347 = 0.41 => 0.41 * 100% = 41% Thus, he or she still need to read around 41% of the book

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
