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
