Well, the question asks to write it as a decimal, (you probably knew I'm going to say this)...
It's a good way to brake it up though.

unklerhaukus · Answer

5/40, and 2/40      have cancelling factors 
so are is easier to convert to decimal than 7/40

solomonzelman · Answer

but you would have to add them, and this would give you the exact same result.

unklerhaukus · Answer

1 + 5/40 + 2/40
=1 + 1/8   +  1/20
=1 + 0.125 + 0.05
=1.175

well you can do it as 47/40 without a calculator too, but yes, that's an easier way to brake it up, if calculator is not allowed.
