2 3/5 divided By 4 1/5
= 13/5 divided by 21/5
= 13/5 times 5/21
the 5s cancel out so,
13/21 is the answer.

Think about the last subtraction question.
First, take the numbers and make them "clean" fractions:
2 3/5 is 10/5 + 3/5, or 13/5.
4 1/5 is 21/5.
So, 13/5 divided by 21/5 is simple: 13/21!

2 3/5=13/5, 4 1/5=21/5
13/5 divided by 21/5= 13/5*5/21=13/21

2 3/5 must first be cionvereted to improper fraction...
so 2x5+3 = 13 keep the denominator the same s u have 13/5
do teh same for the next fraction..
4 x5+1= 21 keep the denominator the same s u have 21/5
so you now have 13/5 divided by 21/5
flip the second fraction upside down and multiply the fractions straight across...so
13/5 x 5/21
13x5 / 5x21 = 65/105
then simplify teh fraction by dividing both top an dbottom number by 5 ...
ANSWER = 13/21

(2 3/5)/(4 1/5)
=(13/5)/(21/5)
=(13/5)*(5/21)
=(13*5)/(5*21)
=13/21
