Answer:
29
Step-by-step explanation:
You do 119-3 because 3 students rode with their parents so then you do 116÷4=29
The correct answer is: c) 46 and 87
Further explanation:
Let us define relatively prime numbers first:
"Relatively prime numbers are those numbers whose greatest common factor is 1"
So,
a) 20 and 76
![20: 1,2,4,5,10,20\\76: 1,2,4,76](https://tex.z-dn.net/?f=20%3A%201%2C2%2C4%2C5%2C10%2C20%5C%5C76%3A%201%2C2%2C4%2C76)
The GCF is 4 so the pair is not relatively prime.
b) 25 and 65
![25: 1,5,25\\65: 1,5,13,65](https://tex.z-dn.net/?f=25%3A%201%2C5%2C25%5C%5C65%3A%201%2C5%2C13%2C65)
The GCf is 5 so the pair is not relatively prime.
c) 46 and 87
![46: 1,2,23,46\\87: 1,3,29,87](https://tex.z-dn.net/?f=46%3A%201%2C2%2C23%2C46%5C%5C87%3A%201%2C3%2C29%2C87)
GCF is 1 so the pair is relatively prime.
d) 63 and 117
![63:1,3,7,9,21,63\\117:1,3,9,13,39, 117](https://tex.z-dn.net/?f=63%3A1%2C3%2C7%2C9%2C21%2C63%5C%5C117%3A1%2C3%2C9%2C13%2C39%2C%20117)
GCF is 9 so the pair is not relatively prime.
Hence, option C is correct
