How would I do 1 and 1/3 over 1/4 times 2/5 over 1/2? On the problem it is phrased:

 

1 1/3 / 1/4  x  2/5 / 1/2

Really confused, please tell me how to solve this!

1 1/3 / 1/4  x  2/5 / 1/2

Remember that 1+1/3  = 4/3...so we have

4/3 / 1/4  x   2/5  / 1/2     and when we divide fractions like this, we just keep the munerator as it is, change to multiplication, and  "flip" the fraction in the denominator...so we have

[4/3 X 4/1 ]  x [ 2/5 x 2/1] = 

16/3  x  4/5 =

64/15

And that's ir...
