to @ report level, can use like:

=1 - (fields!outsla.value / fields!insla.value)

i wouldn't multiply 100 in expression, set textbox format property approriate value, e.g. p0.

enter image description here

the above expression assumes detail row. apply @ in header or footer row, use like:

=1 - (sum(fields!outsla.value) / sum(fields!insla.value))

i tried out first formula in basic report:

the results different example, can see underlying figures in last column , why rounded in p0 column.

edit after comment

you can prevent infinity values using iif statements check 0 insla totals, like:

=1 -(iif(sum(fields!insla.value) <> 0   , sum(fields!outsla.value) / sum(fields!insla.value)   , 0))

-200% correct value particular row based on calculation: 1 - (3/1) = -2 = -200 %. expect be?
