Answer:
4320
Step-by-step explanation:
You need to multiply all of the numbers, hope that helps
If you mean <em>x</em> = 0.666…, then
10<em>x</em> = 6.666…
10<em>x</em> - <em>x</em> = 6.666… - 0.666…
9<em>x</em> = 6
<em>x</em> = 6/9 = 2/3
If you mean <em>x</em> = 0.060606…, then
100<em>x</em> = 6.060606…
100<em>x</em> - <em>x</em> = 6.060606… - 0.060606…
99<em>x</em> = 6
<em>x</em> = 6/99 = 2/33
PEMDAS
Multiplication:
10* -4 / 3*9 = -40 / 27
Addition:
-40 / 27 + 7/6 find common denominator 108
-40*4 / 27*4 + 7*18 / 6*18
-160 / 108 + 126 / 108
-34 / 108
-17 / 54
Subtract:
-17 / 54 - 2/5 common denominator 270
17*5 / 54*5 - 2*54 / 5*54
-85 / 270 - 108 / 270
-193 / 270
-193/ 270 = -0.7148
-8 / 15 = -0.7148 :)
