Question

calculați știe cineva

Answer 1

12/5•1/3=4/5
77/27:33/12=77/27 •12/33= 7/27 •12/3=7/9•4/3=28/27
Pe restul le faci tu dupa modelul asta adica daca ai 1/2:1/3 pe 1/2 il inmultesti cu rasturnatul celui de-al doilea , adk cu 3/1 adk cu 3
*3/100 :30/25=3/100•25/30=1/4•1/10=1/40
*15/14:13/28=15/14•28/13=15/1•2/13=30/13
*45/18:9/12=45/18•12/9=5/3•2/1=10/3
*10:5/4=10/1•4/5=2/1•4/1=8/1=8
*72/10: 18/25=72/10•25/18=12/2•5/3=4/2•5/1=20/2=10
Gata exercitiul !
