Hope this helps!

Answer 2

Write the decimal number as a fraction
(over 1)
19.79 = 19.79 / 1

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

Numerator = 19.79 × 10 × 10 = 1979

Denominator  = 1 × 10 × 10 = 100

Numerator / Denominator = 1979 / 100

Simplifying our fraction

= 1979/100

= 1979/100

= 19  79/100
