Answer 1

this is a very simple question!

so this is what your problem looks like:

2 *      3=      6

--  ..--  ..--

5 *      4=      20

all you do is divide the top 2 numbers together to get the solutions top number. then you do the same to the bottom. now its all about simplifying.

Make a list of all the factors to each number.

6: 1,2,3,6

20: 1,2,4,5,10,20

now you have to find the greatest common factor, which in this case is 2. Now divide each number by 2 (the greatest common factor) to get your simplified fraction.

Tell me if you need further explaining!

Answer 2

1 - 2/5 times 3/4  =  (2*3) / (5*4) = 6/20 = 3/10

#2 - to divide fractions you multiply by the reciprocal of the second one  8/9 times 5/4 =   (8*5) / (9*4) = 40/36 = 20/18 = 10/9
