1 1/5*2,5-3,5:1,4=
2,6kreskaułamkowa 2,5-1 2/3 : 6=

Answer 1

60 i 3/7 - 2,6 * 10 =

= 60 i 3/7 - 26=

= 34 i 3/7




(2/3 + 0,5 : 3) : 5/6=

= (2/3 + 5/10 * 1/3) * 6/5=

= ( 2/3 + 5/30) * 6/5=

= ( 2/3 + 1/6) * 6/5 =

= (4/6 + 1/6) * 6/5=

= 5/6 * 6/5 =

= 1/1 * 1/1=

= 1/1=

= 1




1 i 1/5 * 2,5  - 3,5 : 1,4=

= 1 i 2/10 * 2,5 - 2,5=

= 1,2 * 2,5 - 2,5=

= 3 - 2,5=

= 0,5
