To answer set up a proportion. You are trying to find how many books are in the entire book given 80% of the pages which is 180. Thus you put 80 over 100 and 180 over X(total number of pages). Then you cross multiply to solve for x.
Remember the formula is/of. you have to put 180 pages over x because u don't know the total. then make that equal 80 over 100 to represent 80%. solve for the proportion how the person before me answered
400 yards x 5= 2,000 yards keisha walked. 1 mile equals 1,760 yards. Now to find the 2 miles in yards multiply 1760 x 2= 3,520. So 2 miles equal 3,520 yards. Now subtract 3,520 - 2,000
