1. The missing digit is 7
63,270 ÷ 855 = 74
2. 6 ÷ 8
Fractions are basically division problems
3. 1/10 or 1 over 10
Make them have the same denominators
1/2 - 2/5 = 5/10 - 4/10 = 1/10
4. I believe it’s 13 ½
Since you need to add 4 of the shortest leashes
3+3+3+4½ = 13½
5. 114.7 miles
3.7 x 31 = 114.7
