Answer:

Step 5

Step-by-step explanation:

The mistake is in step 5.

The previous step was

$step \: 4 : 2 + 10 \div 2$

The order operations, PEDMAS, must be applied:

We have Addition and Division here,

Using PEDMAS, we must divide first to get:

$step \: 5 : 2 + 5$

We can now add to get:

$step \: 6: 7$

Therefore the mistake occurred at step 5
