Final answer:
Jane is 11 2/8 inches tall.
Step-by-step explanation:
To find Jane's height, we need to add 1 + 3/4 (Chelsea's height) inches, 1 + 3/8 inches (Carl's height), and 1 + 1/5 inches (Jane's height).
First, we need to convert all the fractions to a common denominator:
3/4 = 6/8
3/8 = 3/8
1/5 = 1/5
Now, we can add the fractions:
6/8 + 3/8 + 1/5 = 15/8 + 3/8 + 8/40 = 26/8 + 8/40 = 34/8 + 8/40 = 42/8 + 8/40 = 50/8 + 8/40 = 58/8 + 8/40 = 66/8 + 8/40 = 74/8 + 8/40 = 82/8 + 8/40 = 90/8 = 11 2/8 inches
So, Jane is 11 2/8 inches tall.
