blondinia [14]

Answer:

35 and 7/12 feet is the combined height of the two records.

Step-by-step explanation:

Height of the indoor pool vault record for men = 20 and 1/6 ft = $\frac{121}{6} ft$

Height of indoor pool vault record for women = 15and 5/12 ft = $\frac{185}{12} ft$

The combined height of the two records :

$\frac{121}{6} ft+\frac{185}{12} ft$

$\frac{121\times 2}{6\times 2} ft+\frac{185}{12} ft$

$\frac{242}{12} ft+\frac{185}{12} ft$

$\frac{242+185}{12} ft=\frac{427}{12}=35\frac{7}{12}$

35 and 7/12 feet is the combined height of the two records.
