Fiona was thinking of a number. Fiona doubles it, then adds 5 to get an answer of 49.2. What was the original number?

22.1
She added 5 so you take away 5 which would be 44.2 then she doubles it another word for multiplication so you do the opposite and divide by 2 and you get 22.1

Answer:

22.1

Step-by-step explanation:

To find the answer we have to work backward:

We start with 49.2 and have to SUBTRACT 5:

49.2-5=44.2

Next, we must DIVIDE by 2:

44.2/2=22.1

To check our answer we can plug it into the problem:

22.1x2=44.2             44.2+5=49.2

I hope this helps :)
