Rewrite 72.3 + (-39.1) by breaking up each of the place values. In this case, the place values are tens, ones, and tenths.
777dan777 [17]

72.3 - 39.1 = 4 tens - 7 ones - 2 tens is the correct order after rewriting.

Given the formula 72.3 + (-39.1)

removing the parentheses:

= 72.3 + (-39.1) (-39.1)

= 72.3 - 39.1

converting decimal numbers to place values

72.3 = 7tens plus 2units plus 3tenths

72.3 = 7(10) (10)

+2(1)+3(1/10)

72.3 =70+2+0.3

Similarly, 39.1

39.1 = 3tens plus 9units plus 1tenth

39.1 = 3(10)+9(1)+1(1/10)

39.1 =30+9+0.1

72.3 - 39.1 = 70+2+0.3 - (30+9+0.1)

72.3 - 39.1 = 70+2+0.3 - 30-9-0.1

72.3 - 39.1 = 70-30+2-9+0.3-0.1

72.3 - 39.1 = 40 - 7 +0.2

Hence after rewriting we get 72.3 - 39.1 = 4 tens - 7 ones - 2 tens
