Answer:
6.666 or 6 2/3 and 9. 333 or 9 1/3
Step-by-step explanation:
5+7 = 12 so 1 part is 1
16/12 = 1.333.. = 1 1/3 1 part is changed when the total is higher
5 x 1 1/3 = 6.666 6 2/3
7 x 1 1/3 = 9. 333 = 9 1/3
Answer:
Step-by-step explanation:
Let A and B stand for the two numbers.
A + B = 16
A/B = 5/7
Rearrange the first and substitute:
A = 16-B
(16-B)/B = 5/7
(16-B) = 5B/7
5B/7 = (16-B)
5B = 7(16-B)
5B = 112 - 7B
12B = 112
B = 9.3333 or 9 1/3
A = (16 - 9.333) or (16 - 9 1/3)
A = 6.6667 or 6 2/3
A + B = 16?
9 1/3 + 6 2/3 = 16 YES
A/B = 5/7 ?
(6 2/3)/(9 1/3) = (20/3)/(28/3) = (20/3)*(3/28)
= (20/28) = 5/7 YES
