Сократите дроби: 10/15, 12/18, 24/48, 28/35, 39/12, 88/99, 18•25/75•12, 120/300, 135/180

Question

Сократите дроби: 10/15, 12/18, 24/48, 28/35, 39/12, 88/99, 18•25/75•12, 120/300, 135/180

Answer 1

10/15=2*5/(3*5)=2/3
12/18=2*6/(3*6)=2/3
24/48=24/(24*2)=1/2
28/35=7*4/(7*5)=4/5=0,8
39/12=13*3/(4*3)=13/4=3,25
88/99=11*8/(11*9)=8/9
(18•25)/(75•12)=(6*3*25)/(25*3*6*2)=1/2
120/300=60*2/(60*5)=2/5=0,4
135/180=45*3/(45*4)=3/4=0,75
