Answer:
127/70
Explanation:
3/5 = 168/280
6/7 = 240/280
4/8 = 35/70 = 100/280
Now, we can add the fractions by adding their numerators and keeping the common denominator:
168/280 + 240/280 + 100/280 = (168 + 240 + 100) / 280 = 508/280
We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 4:
508/280 = (4 x 127) / (4 x 70) = 127/70
Therefore, the sum of the fractions 3/5, 6/7, and 4/8 is 127/70.
