Answer:
The number is 0.2
Step-by-step explanation:
Write an equation for it:
Say that the number was called x
2(x +8) =16.4
Brain added 8 to the number (x) and then doubled it which is the 2
Times out the brackets 2x + 16 = 16.4
Take away 16 from both sides
2x = 0.4
0.4 / 2 = 0.2
Put the number that the decimal is over the place that it is in
example
.5
every space after the decimal is multiplied by 10
tenths place 0.1
hundreths 0.01
thousanths 0.001
etc
so .5 is in the tenths place so the fraction would be 5/10
the decimal is now converted into a fraction
another example
.07 is in the hundreths so it would be 7/100
final example
.25 is in the hundredths place since the last number lands on the hundreths column
it would be 25/100
if possible you can simplify if that is what is needed
