Add the same again
3/6 + 3/6 = 6/6 = 1/1 = 1
7/10 must be added to 3/10 to make 1 whole.
Five-ninths must be added to four-ninths to make a whole.
To find out what must be added to five-eighths to make a whole, you subtract five-eighths from one. A whole can be represented as eight-eighths, so you calculate: ( 1 - \frac{5}{8} = \frac{8}{8} - \frac{5}{8} = \frac{3}{8} ). Therefore, three-eighths must be added to five-eighths to make a whole one.
5/5 is a whole, therefore is you have 3/5 you need another 2/5 to make it 5/5.
To find what must be added to six tenths (0.6) to make a whole (1), you subtract 0.6 from 1. This calculation gives you 1 - 0.6 = 0.4. Therefore, you need to add four tenths (0.4) to six tenths to make a whole.
5/8
four fifths must be added to make it whole
7/10 must be added to 3/10 to make 1 whole.
What must be added to 3 tenths to make 1 whole
Five-ninths must be added to four-ninths to make a whole.
To find out what must be added to five-eighths to make a whole, you subtract five-eighths from one. A whole can be represented as eight-eighths, so you calculate: ( 1 - \frac{5}{8} = \frac{8}{8} - \frac{5}{8} = \frac{3}{8} ). Therefore, three-eighths must be added to five-eighths to make a whole one.
5/5 is a whole, therefore is you have 3/5 you need another 2/5 to make it 5/5.

To find what must be added to six tenths (0.6) to make a whole (1), you subtract 0.6 from 1. This calculation gives you 1 - 0.6 = 0.4. Therefore, you need to add four tenths (0.4) to six tenths to make a whole.
To make a whole number, you need to add the amount that is missing from 3 to reach the nearest whole number. In this case, 3 is already a whole number, so no additional amount needs to be added to make it a whole. Therefore, nothing needs to be added to 3 to make it a whole number.
Since 610 is a whole number, adding any other whole number will also result in a whole number.
2 halves make a whole. So if you have one half then you need another one to make it a whole. 1/2 + 1/2 = 1
