1
K/4 < Z/3 < R/2 ??
statement 1: insufficient No info on k or r
statement 2: insufficient If R=3, Z=4, and K=5, we get 1.20 < 1.25 < 1.50, increasing order If R=-5, Z=-4, and K=-3, we get -3/4 < -4/3 < -5/2, not increasing order
statements 1+2: insufficient If r=2, z=3.5, and k=10, we get 2.5 < 7/6 < 1, not increasing order If r=3, z=3.5, k=4, we get 1<7/6<1.5, increasing order
if r/2>z/3>k/4 is given.....i can write it as 6r/12>4z/12>3k/12.. ?
thanks in advance...!!!
Yes, \(\frac{r}{2}>\frac{z}{3}>\frac{k}{4}\) is equivalent to \(\frac{6r}{12}>\frac{4z}{12}>\frac{3k}{12}\), which is the same as \(6r > 4z>3k\) (you can get this by multiplying the first inequality by 12, which is the least common multiple of 2, 3, and 4).
