Answer:

Option 3. In step 3, she did not subtract one x from the left side

Step-by-step explanation:

we have the repeating decimal

0.272727...

Convert to fraction number

step 1

Let

x=0.272727...

step 2

Multiply by 100

100x=27.272727...

step 3

Subtract x from 100x

100x-x=27

99x=27

step 4

Find the value of x

x=27/99

therefore

Manda's work is not correct

In step 3, she did not subtract one x from the left side

Aleonysh [2.5K]
Something like physics, you want to not have such a specific major because you can always change your mind later on. It might take around 10ish years, but that is a rough estimate.
