Question

Solve 5 ones 3 tenths -0.53

Answer 1

5.3 - 0.53 = 4.77

because 5.3 - 0.5 = 4.8, and 4.8 - 0.03 = 4.77.

Answer 2

The answer is 4.77

Explanation:

In order to determine the result, we have to know about the notation numbers. In a rational number, every position number has a notation.

I have attached an image that shows some notations.

So, according to the image, we have to change "5 ones 3 tenths":

5 ones 3 tenths= 5*1+3*0.1=5+0.3=5.3

Then:

=5.3-0.53

=4.77

Finally the answer is 4.77
