Brady buys 3 gallons of fertilizer for his lawn. After he finishes spraying the lawn, he has 1 quart of fertilizer left over. How many quarts of fertilizer did Brady spray on his lawn?
We know that a gallon of fertilizer is 4 quarts of fertilizer. Then, 3 gallons is 12, because 3x4=12.
However, he sprayed his lawn, and now only has 1 left. That means that of the 12 he had in the beginning, he only has 1. Meaning he used 11 quarts.
Brady buys 3 gallons so you do 4x3= 12 quarts but now he haves 1 quart left so do 12-1=11 so your answer is 11 quarts.
Explanation: 3 gallons=12 quarts because 1 gallon= 4 quarts. So, you had to multiply 3 by 4 and get 12 total quarts. Then, you had to subtract the 1 quart left over. Here are the steps to help you even further:
Steps:
Step 1: multiple to find the total number of quarts: 3 * 4 = 12 total quarts.
Step 2: subtract to find how much was sprayed: 12 - 1 = 11 quarts were sprayed.
Step 3: your answer in quarts: 11 quarts of fertilizer.
1 gallon = 4 quarts
3 gallons = ? quarts
