Ateacher let her students grade their math quizzes. •jon wrote 13 out of 18 •jim wrote .7 (repeated .7) •joe reduced his to 5/6 who had the higher grade?

Joe

Step-by-step explanation:

Jon wrote 13 out of 18

Dividing 13 by 18 we get, decimal form

Jim wrote .7 (repeated .7)

0.777..........

Joe reduced his to 5/6

Dividing 5 by 6 we get, decimal form

These numbers are irrational numbers

0.833......>0.777........>0.722......

So, Joe had the higher grade.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

2x^2+5x+17

your welcome. : )
