Question

Natasha was thinking of a number.

Answer 1

Answer:

28.1

Step-by-step explanation:

You can answer questions like this by working backwards.

To do this we can divide 78.2 by 2 and that gets us 39.1

Now we have to subtract 11 from it and that gets us our final answer:

28.1

Answer 2

Answer:

She was thinking of the number 28.1

Step-by-step explanation:

Since we do not initially know what number Natasha was thinking of we have to start with 78.2. From here we have to do the reverse operations of what Natasha did.

So we would divide 78.2 by 2 which gives us 39.1

Then we minus 11 from that and we get 28.1
