Answer:

Required ratio = \frac{1}{4}

Step-by-step explanation:

In a bag of 412 peanut candies 20% are brown. 20% are yellow 20% are blue 20% are red 10% are orange 10% are green.

Brown peanuts = 20% of total

                          = 0.2 \times 412

                          = 82 peanuts

Yellow peanuts = 82 peanuts

Blue peanuts = 82 peanuts

Red peanuts = 82 peanuts

Orange peanuts = 41

Green peanuts = 41

We have to find the ratio of orange peanuts to yellow and blue.

Total number of yellow and blue peanuts = 164 peanuts

Total number of orange peanuts = 41 peanuts

Required ratio =\frac{41}{164}

Required ratio = \frac{1}{4}
