The basic idea is that multiplying by 10 just moves the decimal point one place to the right. It makes the number bigger.
4.8 x 10 = 48
4.8 x 10 x 10 = 48 x 10 = 480
Each time you multiply by another 10, the decimal point moves one more time.
The expression says you're going to multiply by 10 five times in a row. So that will move the decimal point 5 places to the right.
So what do you get if you move the decimal in 4.8 five places to the right?

Find out how much money did she start with.
To proof
let us assume that the money she had be x.
As given
woman spent two thirds of her money
Money she had after spent two thirds of her money = Total money - money spent
As given she lost two thirds the remainder
we get
Money she had after lost two thirds the remainder = Money she had after spent two thirds of her money - she lost two thirds the remainder
As given
she had $4 left
thus
x = $36
she start with $36.
Hence proved
