Question

If Daniel is 2 1/2 years old and Chris is 2 years old how old is Daniel in 15 years and Chris in 14 years old

Answer 1

Add Daniel's current age and 15

Then add Chris' current age and 14
------------------------------------------------------------------------------------------------------
Daniel: 

$2 \frac{1}{2} + 15$

Write mixed number as an improper fractions and add 1 as a denominator for 15.

$\frac{5}{2} + \frac{15}{1}$

Both denominators should be of same number so, multiply $\frac{15}{1}$ by 2

$\frac{5}{2} + \frac{30}{2} = \frac{35}{2}$

Write $\frac{35}{2}$ as a mixed number which gives us:

$17 \frac{1}{2}$

Daniel's Age in 15 years would be $17 \frac{1}{2}$
------------------------------------------------------------------------------------------------------
Chris:

2 + 14 = 16

Chris' age in 14 years would be 16
