Analyze Manda's work. Is she correct? If not, what was her mistake? Yes, she is correct. In step 2, she needed to multiply both sides by 10. In step 3, she did not subtract one x from the left side. In step 4, she did not simplify her fraction. 1. X=0.27272727273 2. 100x=27.2727272 3. 100x= 27 4. X=27/100

Her mistake was in steps 3 and 4.

x = 3/11

Step-by-step explanation:

No. She isn't correct.

Step 1: Let x = 0.2727272727 ...Equation 1

Step 2: Multiply both sides by 100.

100x = 27.27272727 ...Equation 2

Step 3: Subtract equation 1 from equation 2.

100x-x = 27.27272727-0.2727272727

99x = 27

Step 4: Divide both sides by 27.

99x/99 = 27/99

x = 3/11
