Answer:

3.1

Step-by-step explanation:

3 1/2=3.5

2/5=0.4

3.5-0.4=3.1

Answer:

3 1/10

Step-by-step explanation:

You can make 3 1/2 an improper fraction and then subtract it from 2/5

We do across so 7 x 5 is 35. 2 x 2 is 4. 2 x 5 is 10. 35 - 4 is 31. 31/10 simplified is 3 1/10.

So your answer is: 3 1/10
