85 or 135

Explanation:

1.6 is 16 divided by 10 which can be written 1610
Divide numerator and denominator by the same thing (cancel) in this case divide by 2 to give 85
Eight fifths is 1 whole (five fifths) and 3 fifths so as a mixed number 135

85 ( as a fraction )

I have deliberately shown this as it demonstrates a very useful technique. The short cut is as per the other solution.

Explanation:

1.6 is the same as 1+610

Multiply by 1 and you do not change the value. However, 1 comes in many forms.

[1×1]+610 [1×1010]+610

1010+610 = 10+610 = 1610

To simplify the fraction divide top and bottom by 2

161016÷210÷2=85
