Answer:
11
Step-by-step explanation:
Part 1
Integers divisible by 7 = [tex]\frac{131}{7}[/tex] -[tex]\frac{31}{7}[/tex]
= [tex]\frac{131}{7}[/tex] - [tex]\frac{28}{7}[/tex]
= 18.714 - 4
= 18 - 4
=14
Part 2
smallest number divisible by both 6 and 7 = 42
largest number divisible by both 6 and 7 = 42
Integers divisible by both 6 and 7 = [tex]\frac{126}{42}[/tex] = 3
Part 3
Number of integers divisible by 7 but not by 6 = 14 − 3 = 11
