To solve the problem, we can break it down into two parts.
Part A: Basic Fact To find out how many seeds will be planted in each row, John can use the fact that he has 2,700 seeds to divide by 9 rows. The mathematical expression that represents this operation is:
\[ 2700 ÷ 9 = ? \]
From the options provided, the closest basic fact that can help John is:
\[ 270 ÷ 9 = 30 \]
This is because if you understand that 2,700 is ten times larger than 270, you can use this fact and then multiply the result accordingly.
So the appropriate choice from the options would be:
270 ÷ 9 = 30
Part B: How many seeds will John plant in each row? To find out how many seeds John will plant in each row:
\[ 2700 ÷ 9 = 300 \]
Thus, John will plant 300 seeds in each row.
