Answer :

Write the decimal number as a fraction
(over 1)
9.85 = 9.85 / 1

Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's

Numerator = 9.85 × 10 × 10 = 985

Denominator = 1 × 10 × 10 = 100

Numerator / Denominator = 985 / 100

Simplifying our fraction

= 985/100

= 197/20

= 9  17/20
