Mr. Ahn buys buys relishes for lunch party. He buys 7/8 pound of pickles and 9/10 pound of olives. How much altogether do these weigh?
The answer is 41/40 or 1 1/40.
7/8 = 35/40
9/10 = 36/40
Add the two fractions and simplify.
Neither.
To find the total weight of pickles and olives, we need to add their weights together.
Mr. Ahn bought 7/8 pound of pickles and 9/10 pound of olives.
To add fractions, we need to have a common denominator. In this case, the least common multiple of 8 and 10 is 40.
First, let's convert the fractions to have a denominator of 40.
For the pickles:
7/8 = (7/8) * (5/5) = 35/40
For the olives:
9/10 = (9/10) * (4/4) = 36/40
Now that both fractions have a denominator of 40, we can add them together:
35/40 + 36/40 = 71/40
But we need to simplify the fraction. The greatest common divisor (GCD) of 71 and 40 is 1, so we can't simplify further.
The total weight of the pickles and olives is 71/40 pounds.
