Nora planted 70 seeds. 60% of them sprouted.
How many seeds DID NOT sprout?
4200
2800
42
28
To find the number of seeds that did not sprout, we need to calculate 40% of the total number of seeds, which is 70.
40% of 70 = (40/100) * 70 = 0.4 * 70 = 28
Therefore, there are 28 seeds that did not sprout. The correct answer is 28.
