Answer:
108
Step-by-step explanation:
so first of all the blue counters are 23/50. we want to make this fraction out of 300 because there are 300 counters. therefore, you multiply the numerator and denominator by 6. This gets you 138/300, so there are 138 blue counters.
since there are 138 blue counters the other 162 counters must be red and white. the ratio from red to white is 2:1, which means there are 3 parts in total ( because 2+1 is 3). so to get one part u divide 162 by 3. this gets you 54. so to get red u multiply that by 2 because red has two parts. this leaves you with 108. to double check its right u add 108+54+138=300.
