It takes 3/11 pounds of seeds to plant one grow sunflowers. what is the correct answer to find the number of rows of sunflowers that can be planted with 3/4 pound of seats?

3/11 pounds of seeds = 1 row of sunflowers
3/4 pounds of seeds = x
x stands for the unknown number of rows of sunflowers
To find x : Cross multiply
3x/11 = 3/4
3(11) = 4(3x)
12x = 33
Divide both sides by 12 ( so that we would be left with only x)
12x/12 = 33/12 ( where we have 12x/12 ; 12 is common in both the numerator and denominator so they will cancel out each other).
We are left with : x = 33/12
x= 2.75
x = 3 (approximated to a whole number)
Therefore: number of rows of sunflowers is 3 ☺
