3445 / 5 = 689
15 / 5 = 3
689/3
Answer:
1. 6
2. 1
3. 5
Step-by-step explanation:
You can find the GCF by finding the prime factorization of the numbers.
1. 12 and 18
12= 2*2*3
18=2*3*3
They both have 2 and 3 in common, so their GCF is 2*3 or 6.
2. 9 and 35
9= 3*3
35= 5*7
Although they don't have any prime numbers in common, all numbers have the factor one in common, so they're relatively prime but their GCF is 1.
3. 15 and 25
15 = 3*5
25= 5*5
They have one 5 in common so their GCF is 5.
He can make 32 sandwiches. Since he uses 1/8 pound of cheese for each sandwich, he can make 8 sandwiches using 1 pound of cheese (1/8 x 8 = 1). Now that you know he can make 8 sandwiches with 1 pound of cheese, multiply 8 (this is the sandwiches) by 4 (pounds of cheese).
