Question

Jay and David are Calculating their combined height Jay is 5 3/4 feet tall, and David is 6 1/8 feet tall. What is jay and David's combined height?

Answer 1

Answer: $\dfrac{95}{8}\ ft$

Step-by-step explanation:

Given

The height of Jay is $5\frac{3}{4}\ ft$

The height of David is $6\frac{1}{8}\ ft$

Converting mixed to fraction and add the two heights for combined height

$\Rightarrow \dfrac{5\times 4+3}{4}+\dfrac{6\times 8+1}{8}\\\\\Rightarrow \dfrac{23}{4}+\dfrac{49}{8}\\\\\Rightarrow \dfrac{46}{8}+\dfrac{49}{8}\\\\\Rightarrow \dfrac{46+49}{8}=\dfrac{95}{8}\ ft$

Thus, the combined height of the two is $\frac{95}{8}\ ft$
