class is 5 :. Now solve the proportion: frac2400xfrac415 x9000mbox crayons, a typist can type 120 words in 100 seconds. Now, all these types of problems can get much more difficult (and we will see later how to use two variables with some of them but its important to take baby steps with them. .

We see that there are 270 ounces of X and 990 of Y in solution. (x) per (y as in (x) for every (y) Multiplication, or (xtimes y). Lets see if it works: (displaystyle frac frac5406,90,surd ) hint: For any problem with weighted averages, you can multiply each value by the weight in the numerator, and then divide by the sum of all the weights that youve used. Answer12 12 is 75 of what number? (displaystyle (displaystyle n29,n130,n231) Again, we assign (n) to the first number, (n1) to the second, and (n2) to the third, since they are consecutive numbers. We just need to add the least number and the greatest to get. That is, for the proportion, a:b c:d,  a x d b.

Again, you can always add distances; look at them separately first, and then you can put them together to equal the total distance ( 100 ).
