90 and 91 are relatively prime, the way they can be relatively prime is to have no factors in common-
90- 2x3x3x5
91- 7x13
Answer:
11
Step-by-step explanation:
So if he already biked 25 miles we can subtract 80 and 25 which will get a total of 55. if we divided 55 miles to the rest of the 5 days he will have to bike 11 miles each day
X/y = 2/3 / 6/7
= 2/3 * 7/6
= 14/18
= 7/9
