The heights of 4 students are 5 1/2 feet, 5.35 feet, 5 4/10 feet and 5.5 feet. what is the height in feet of the shortest student written as a decimal?

also, put these in order from least to greatest:
-1/5, -2/3, 2, 0.4

f

step-by-step explanation:

f

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
