A group of people in a city decide to measure the total distance of a walking path and put up distance markers for the people who walk. On one particular day they put up markers on 78 of a mile of the way. The next day they put up markers on another 12 of a mile. What is the total distance they have completed?
Please help! I got 11/8 but idk if its right!
and the 78 is supposed to be 7/8 and the 12 is supposed to be 1/2:,)
correct,
7/8 + 1/2
= 7/8 + 4/8
= 11/8
and by the way you may want to write 11/8 as 1 3/8
Not necessary to write 11/8 as 1 3/8.
Both represent the same number, as a matter of fact,
1 3/8 is actually a "useless" notation, since for most arithmetic calculations
you would have to change it to 11/8
I simply do not know what her teacher wants for notation.
well it is says "___ of a mile" so I assume it shouldn't be a mixed number but I could be wrong
To find the total distance that the group has completed, we need to add up the distances they covered on the different days.
On the first day, they put up markers on 7/8 of a mile.
On the second day, they put up markers on 1/2 of a mile.
To find the total distance, add these two fractions together:
7/8 + 1/2
To add fractions, we need a common denominator. The easiest way to find a common denominator for 8 and 2 is to multiply them together, which gives us 16.
Now, rewrite the fractions with the common denominator:
7/8 becomes 14/16 (multiply the numerator and denominator by 2)
1/2 stays as 1/2 (already has the common denominator)
Now we can add the fractions:
14/16 + 1/2 = (14 + 8) / 16 = 22/16
The fraction 22/16 can be simplified by finding the greatest common divisor (GCD) of the numerator and denominator, which is 2 in this case:
22/16 = (11/8) * (2/2) = 11/8
So, the total distance that the group has completed is indeed 11/8 of a mile. Your answer is correct!
