Answer:
The whole number is 5.
To subtract the fractions, we need to find a common denominator. The smallest common denominator for 2 and 10 is 10.
Converting the mixed number into an improper fraction:
6 1/2 = (6 x 2) + 1/2 = 12/2 + 1/2 = 13/2
13/2 - 9/10 = (65/10) - (9/10) = 56/10
Simplifying the fraction:
56/10 = 5 6/10 = 5 3/5
Therefore, the answer is 5 and the explanation above shows how the answer was obtained step by step.
