Answer:

3\frac{3}{10}

Step-by-step explanation:

Given: diameter = 6\frac{3}{5}

This is a mixed number.

We have to convert mixed numbers to improper fractions.

6*\frac{5}{5}+\frac{3}{5} \\ \frac{30}{5}+\frac{3}{5}=\frac{33}{5}

diameter = 33/5

Now diameter = 2*radius so we divide 2 by diameter to get our radius.

\frac{33}{5} /2=\frac{33}{5}*\frac{1}{2} =\frac{33}{10}

Improper fraction back to a mixed number.

10 can go into 33, 3 times so left with a 3 remainder.

\frac{33}{10}=3\frac{3}{10}

Answer & Step-by-step explanation:

First, we will multiply 5 by 28 to find out the total number of ages in the room.

5 * 28 = 140

Now, we will multiply 6 by 29 to find out the total number of ages in the room after the new person comes in.

6 * 29 = 174

Now, in order for us to find the age of the new person, then we will subtract 140 from 174.

174 - 140 = 34

So, the person that entered the room is 34 years old.
