Question

Place the following in increasing order:  3/5  70%   0.8  11/20  65%   0.09. How would you explain your process to someone else?

Answer 1

I converted all to decimal

x%=x/100
so

3/5=6/10=0.60
70%=70/100=7/10=0.70
0.8=0.80
11/20=5.5/10=0.55
65%=65/100=6.5/10=0.65
0.09=0.09

so increasing
smallest to largest
0.09, 0.55, 0.60, 0.65, 0.70, 0.80
or
0.09, 11/20, 3/5, 65%, 70%, 0.8
