30/78 simplified is 15/39
The correct answer is option A
Answer:
approximately 72.35 minutes
Step-by-step explanation:
there are 1609.344 meters in a mile
john ran 100 meter - which would be 16.09 per mile
9.88 seconds x 16.9 = 166.97 seconds per mile
166.97 seconds x 26 miles = 4341.22 seconds
4341.22 seconds / 60 = 72.35 minutes
The answer is: "
41 / 11 " ; or, write as: "
41 : 11 " .
__________________________________________________________Explanation:__________________________________________________________72/99 = (72÷9) / (99÷9) = 8/ 11 .
So, 3.727272727272... = "3

" .
→ "3

" = [(11 *3) + 8] / 11 = (33 + 8) / 11 = 41 / 11 .
__________________________________________________________ "41 / 11" cannot be simplified any further; so the answer is:
__________________________________________________________ "
41 / 11 " ; or, write as: "
41 : 11 " .
