Question

kaits younger sister is 2feet and 9 inches tall.katie is 5 feet and 4 inches tall . what is the difference between their two hights​

Answer 1

`2\ ft\ 7\ in`

Explanation:

we know that

To find the difference convert the dimensions to inches

Remember that

`1\ ft=12\ in`

so

katie's younger sister hight is

`2\ ft\ 9\ in=2*12+9=33\ in`

katie's hight is

`5\ ft\ 4\ in=5*12+4=64\ in`

Find the difference

`64\ in-33\ in=31\ in`

Convert to feet and inches

`31\ in=31/12=(24/12)+(7/12)=2+(7/12)=2\ ft\ 7\ in`
