Answer:
1
Step-by-step explanation:
21 = 3*7
65 = 5*13
CGF: to find the greatest common factor, multiply those factors both numbers have in common
GCF :1 since there are no factors in common
Answer: 1 ✔
The factors of 21 are: 1, 3, 7, 21
The factors of 65 are: 1, 5, 13, 65
Then the greatest common factor is 1.
They both contain a one in their factors so the GCF for both is 1.
60,000
Jane-2000
Peter-ratio of 5=25000
Marta-ratio of 7=35000
25000+35000
60000
5/4 or 1 1/5
remove the zeros and you get 5/4 or 1 1/5
-5x +15 ≤ 20
