....................

(3 6/10 - 1 2/3): (4 1/15 - 2 7/9) = (3 3/5 - 1 2/3):(4 1/15 - 2 7/9) = (3 9/15 - 1 10/15):(4 3/45 - 2 35/45) = (2 24/15 - 1 10/15):(3 48/45 - 2 35/45) = (1 14/15):(1 13/45) = (29/15):(58/45) = (29/15) * (45/58) =  3/2 = 1,5

My best friend's name is Pete
he is a very good friend
we have known each other for many years
he has short blonde hair and light blue eyes
he has a nice and kind smile
his face is covered with freckles
he is a very busy person because he studies very hard at school
sometimes he helps me with some subjects if I don't understand them
he  wakes up early and streches
then, he goes to school 
after school, sometimes we do homework together 
and then, he goes to his karate club
he really likes karate and I think it is a useful skill
karate is also good for the body and overall health
sometimes it can also be a self defence method
we love the same books and movies 
he likes star wars, and so do I
he likes books about adventures like me
sometimes we recommend each other books
he is a good person, he never says anything rude about anyone
Pete is also very kind to older people, kids and animals!
I love spending time with Pete!
