Final answer:
To calculate the total amount of seed needed by the landscaper for two fields, add the weights of both fields. The total seed needed is 91/4 tons.
Step-by-step explanation:
To calculate the total amount of seed needed by the landscaper for two fields, First Field and Second Field, we need to add the weights of both fields. First, convert the mixed numbers to improper fractions.
First Field: 12 1/2 tons = 25/2 tons
Second Field: 10 1/4 tons = 41/4 tons
Now add the fractions: 25/2 + 41/4 = 50/4 + 41/4 = 91/4 tons
The total seed needed for both fields is 91/4 tons.
