A basket contained 75 brown eggs. 40% of them were used-up, and a third of them remaining were rotten and thrown out. What fraction of the initial number of brown eggs remained in the basket finally?

4/15

Step-by-step explanation:

40% is the same as .4.

.4 x 75 = 30

1/3 x 75 = 25

30 + 25 = 55

75 - 55 = 20

20 / 75

Simplify. Divide by 5.

4/15

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
