Question

2/0,(3)•0,(4)+2/0,(4)•0,(5)+2/0,(5)•0,(6)​

Answer 1

2/(0,3)•(0,4)+2/(0,4)•(0,5)+2/(0,5)•(0,6)= 2/(0,4)•(0,3)+2/(0,4)•(0,5)+2/(0,5)•(0,6)=5•(0,3)+5(0,5)+4(0,6)= 1,5+2,5+2,4=6,4

Answer 2

It seems like you're trying to perform some mathematical operations, but the expression you provided contains divisions by zero, which are undefined in mathematics. Division by zero is not a valid operation because it leads to mathematical inconsistencies and undefined results.

In the expression you provided:

2/0,3 • 0,4 + 2/0,4 • 0,5 + 2/0,5 • 0,6

All the divisions by zero (2/0,3, 2/0,4, and 2/0,5) are undefined, and you cannot perform arithmetic operations with them. If you have a different mathematical expression or if there's a specific calculation you'd like to perform, please provide more details, and I'd be happy to help.
