.A food company randomly selected 60 pistachios from a recent shipment. The company found that 3 pistachios should be discarded. A large bag of pistachios hold about 380 pistachios. Predict how many of the 380 pistachios should be discarded

Respuesta :

We can use ratios to compare these numbers.

60 pistachios:3 discarded
380 pistachios: ? discarded

60 x 6 1/3=380 total
3 x 6 1/3=19 discarded

19 of the 380 pistachios should be discarded. Another way to figure out the solution is by calculating the percentage of discarded pistachios then applying it (60/3 = 5% discarded).
