In order from smallest to biggest, this is the order in which the following numbers would go --
0.07 (Or, 7%)
0.34 (Or, 34%
0.4 (Or, 40%)
0.56 (Or, 56%)
(Remember, to get the answer, you would multiply each decimal by 100 and then compare them all and put them in order that way. That's how I find it easiest to put decimals in smallest to biggest :D)
