edurado owned 6/7 of a family business. he sold 1/5 of the business to his son what portion of the business does he still own?
6/7 * 4/5 = 24/35
To find out what portion of the business Eduardo still owns, we need to subtract the portion he sold to his son from the portion he originally owned.
Eduardo initially owned 6/7 of the business.
He sold 1/5 of the business to his son.
To determine the portion he still owns, we calculate:
Fraction Eduardo still owns = 6/7 - 1/5
To subtract fractions with different denominators, we need to find a common denominator. In this case, we can use the least common multiple (LCM) of 7 and 5, which is 35.
Converting the fractions to have a common denominator of 35:
(6/7) * (5/5) = 30/35
(1/5) * (7/7) = 7/35
Now, we can subtract the fractions:
30/35 - 7/35 = 23/35
Therefore, Eduardo still owns 23/35 of the business, or approximately 0.657 or 65.7%.
