Answer:
Step-by-step explanation:
chris is 11 5/6 years old
marian is 1 1/3 years younger...
(11 - 1) = 10 : (5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2)...so marian is 10 1/2
jane is 1 1/4 years younger then marian...
10 1/2 - 1 1/4...
(10 - 1) = 9 : (1/2 - 1/4 = 2/4 - 1/4 = 1/4)....so Jane is 9 1/4 years <==
