Answer:
7
Explanation
From the question we are told that 35 plants are in 5 rows, using proportion, we are to determine the number of plants that will be in 1 row;
Using proportion;
35 plants = 5 rows
x plants = 1 row
Cross multiply
5 * x = 35 * 1
5x = 35
Divide both sides by 5;
5x/5 = 35/5
x = 7
Hence the missing number that will complete the proportion is 7.
