Question

The shortest adult skeleton at Mütter stands 3 1/2 feet. The tallest skeleton in the museum stands 2 1/7 times taller. How tall is the tallest skeleton?

Answer 1

you add 3 1/2 to 2 1/7 to get the tallest skeleton.

3 1/2 = 7/2 and 2 1/7= 15/7

First you find common denominators for both fractions. 2 and 7 go into 14.

2 times 7 equals 14
7/2 * 7 = 49/14

7 times 2 equals 14
15/7 * 2 = 30/14

49/14 + 30/14= 79/14

then you simplify 79/14.... 14*5= 70 and 9 are left over. 5 9/14
