The integer number that represents the changing in his account balance from beginning to end is of -20.
<h3>Which numbers belong to the set of integer numbers?</h3>
Non-decimal numbers, either positive or negative numbers, also zero, belong to the set, which can be represented by:
Z = {..., -3, -2, -1, 0, 1, 2, 3, ...}
A change can be represented by the <u>final value subtracted by the initial value</u>. For this problem, we have that:
- The initial balance is of $20.
- The final balance is of $0.
Hence the change in the balance is:
0 - 20 = -20.
And the integer is -20.

3/5+1/2=___
To add them together, convert both fractions so they have the same denominator.
3/5=6/10 and 1/2=5/10
6/10+5/10=11/10, or 1 1/10
1/2+3/8=___
Same for this one- convert both fractions so they have the same denominator.
1/2=4/8 and 3/8 stays the same
4/8+3/8=7/8
1/2+2/5
And again, convert both fractions so they have the same denominator.
1/2=5/10 and 2/5= 4/10
5/10+4/10=9/10
Hope this helps :-)
