Answer:
1 4/5
Step-by-step explanation:
Convert 1/2 to tenths. 1/2 = 5/10 which reduces back to 1/2
borrow 1 from the 6 to make 5/10 greater than 7/10
5/10 + 10/10 = 15/10
The 6 1/2 has become 5 and 15/10
5 15/10 Subtract 4 7/10
4 7/10
1 8/10 Reduce the fraction by dividing top and bottom by 2
1 4/5
