The following mantissa and exponents are represented in twos complement form using 8bits each.

Mantissa: 10010000
Exponent: 00000001

This is how I tried it,

1.0010000 x 2^1
10.010000

Converting this decimal point binary to denary:

-2.25

But the answer is supposed to be -1.75, what have I done wrong?
