Problem

Conversion of mixed fractions into decimal numbers \$16 7/2\$

Step

Given Mixed Fraction

\$16 7/2\$

Hint

Firstly, we need to convert a mixed fraction into a improper fraction.

Step

Add the result to the numerator (7):

\$32 + 7 = 39\$

Step

The new numerator is 39, and the denominator remains 2.

Step

Then the improper fraction is

\$39/2\$

Step

To convert this fraction into a decimal number, divide the numerator by the denominator

\$39/2 = 19.5\$

Step

So, the decimal representation of the mixed fraction \$16 7/2\$ is 19.5

Answer

Option

Sumup

\$20.6\$

Choice.C

This is incorrect as it simplifies to 19.5, not 20.5

\$20.5\$

Choice.D

This is incorrect because the numerator should be \$39/2\$,not 21.2

\$21.2\$
