Answer:
Step-by-step explanation:
For the three fractions;
the three numerators must be different.
they must add up to give 1.
Since there is no information given of the denominators of the fraction, we will assume the denominators can be the same.
So, we can have the three fractions as;
Pick a common denominator. then think of three different numerators that will sum the fraction to 1.
the common denominator - 7
numerators - 1,2,4
We have the equation as;
