  • Could you please check my math?

    Alright, so my 5 years of union apprenticeship school has started and I'm excited for it. I'm taking math now and wanted to make sure I had these right.

    1. 3 1/5 x 1 1/4 x 1 1/3 = ? I got 5 1/3.

    2. 11 1/4 divided by 2 1/2 = ? I got 4 1/2.

            Aaron,

            Are you allowed to convert them to decimals to figure them out? It makes it much faster if you are doing them in your head.

              looks good to me, but I did it in using decimal points, It has been a number of years on the fractions and working them out that way,

              3.2 X 1.25 X 1.33 = 5.32

              11.25 / 2.5 = 4.5

                Thanks Woussko, Mark, and BHD.

                Mark I'm not sure if I've been shown that way yet.

                2 4/9 x 7 1/2 divided by 3 2/3 = ? I got 5.

                  Aaron, fractions are all a matter of finding the common denominator.

                  1/3 + 4/5

                  In this case its 15 (3x5).

                  So 1/3 is the same as 5/15. 4/5 is the same as 12/15. 12+5=17, so the answer is.....

                  1/3 + 4/5 = 17/15 (or 1 2/15)

                  Multiplying and dividing is easy too. 1/3 x 4/5...multiply the top numbers together...4. Multiply the bottom numbers....15. So the answer is...

                  1/3 X 4/5 = 4/15

                      Mixed numbers are fractions.

                      1 3/5 is the same as 8/5.

                          Translate to fractions first, the rest is easy.

                          22/9 x 15/2 รท 11/3 = 30/6...which is 5.

                            I'm too old for math



                            Besides, all I need is addition and subtraction, a little multiplication and I'm good for business.

                              Yeah I do translate them to fractions first.

                              If ya could hold on a few minutes I'm gonna run and grab my paperwork.

                              I'm stuck on a few and hoped you could break them down alil bit for me.
