Question

5-2/5=? 6-3/7=? 8-2/3=?

Answer 1

5-2/5=(4+1-2/3)=4+5/5-2/5=4 5/5-2/5=4 3/5

6-3/7=(5+1-3/7)=5+7/7-3/7=5 4/7

8-2/3=(7+1-2/3)=7+3/3-2/3=7 1/3

Answer 2

Let's solve each of these expressions step by step:

1. 5 - 2/5 To subtract a fraction from a whole number, we need to find a common denominator. The common denominator here is 5. So, we rewrite the expression as follows: (5 * 5 - 2) / 5 = (25 - 2) / 5 = 23 / 5

2. 6 - 3/7 Again, we need to find a common denominator, which is 7 in this case. So, we rewrite the expression as follows: (6 * 7 - 3) / 7 = (42 - 3) / 7 = 39 / 7

3. 8 - 2/3 To subtract a fraction from a whole number, we need to find a common denominator. The common denominator here is 3. So, we rewrite the expression as follows: (8 * 3 - 2) / 3 = (24 - 2) / 3 = 22 / 3

So, the results are:

1. 5 - 2/5 = 23/5
2. 6 - 3/7 = 39/7
3. 8 - 2/3 = 22/3
