STEP - BY - STEP EXPLANATION
What to find?
Whole number to substitute for x in each list of numbers, so that the numbers are ordered from
least to greatest.
Given:
STEP 1
Choose a number and test-run it.
Let's check the number " 6".
STEP 2
Substitute the number and convert to decimals.
That is;
6/20 =0.3
2/6 =0.333
39% = 0.39
6/8 = 0.75
Clearly;
0.3 < 0.333< 0.39 < 0.75
Hence, when x=6 the numbers are ordered from least to greatest.
ANSWER
x = 6
