Step-by-step explanation:
2(l+w)=112.8
l+w=112.8/2
36.9+w=56.4
w=56.4-36.9
w=19.5

Answer:
a) 8 < 9 < 10 1/2
b) 10 1/2 > 9 > 8
Step-by-step explanation:
We can use inequalities to order shoe sizes. We need to know what the symbols mean, for example < means "is lower than" while > means "is greater than". We know that 8 is lower than 9, and 9 is lower than 10 1/2 (which can be written also as 10.5), so we can write:
a) 8 < 9 < 10 1/2
The other way around would be to say that 10 1/2 is greater than 9, and 9 is greater than 8, which means:
b) 10 1/2 > 9 > 8
