Answer:
7.549, , 8.59, 8
Step-by-step explanation:
You notice the last 2 in the sequence are decimals. So you convert everything else to decimals too.
So begin with dividing 171/20 which gets you 8.55
Then convert the second fraction to a regular fraction, by multiplying the denominator by the bigger number beside it, 8.
So 8 * 11 = 88
Then add the numerator to the new product.
88 + 7 = 95
Then you have your new numerator.
Take that and divide by 11
95/11 = 8.63
So from least to greatest is
7.549, , 8.59, 8
