If 12 counters ae 2 fifths of a set?
If we are looking at this strictly mathematically then there are 30 in the set. if 12 is 2 fifths. divide it by 2 give you 6. Which is 1 fifth. Multiply that by 5. gives you the full set 5 * 6 = 30
If 12 counters are two fifths then what is the one?
30
How many blue counters must be added so that the ratio of yellow counters to total counters is 1 to 6?
Let the number of Yellow counters you already have is Y Let the number of non-yellow counters you already have is Z Then the current ratio of Yellow counters to the total counters is Y : Y + Z Let the number of Blue counters you add be B After they have been added, the ratio of Yellow counters to the total counters is Y : Y + Z + B This is 1 : 6 Thus Y = 1 and Y + Z + B = 6 → Z + B = 5 Which means that for the Yellow counters you have you will have five times as many counters made up of whatever non-Yellow counters you originally had plus the Blue counters you added. Thus to find out how many Blue counters to add, take the number of Yellow counters, multiply it by 5 and subtract the number of non yellow counters you originally had. examples: You had 6 Yellow counters Add 6 × 5 - 0 = 30 Blue counters Which gives you 6 Yellow and 30 Blue counters → ratio Yellow : total counters = 6 : 30 + 6 = 6 : 36 = 1 : 6 You had 4 Yellow counters and 6 Red counters Add 4 × 5 - 6 = 14 Blue counters Which gives you 4 Yellow counters, 6 Red counters and 14 Blue counters → ratio Yellow : total counters = 4 : 6 + 14 + 4 = 4 : 24 = 1 : 6 You had 4 Yellow Counters, 2 Blue counters and 3 Red counters Add 4 × 5 - (2 + 3) = 15 Blue counters Which gives you 4 Yellow counters, 3 Red counters and 2 + 15 = 17 Blue counters → ratio Yellow : total counters = 4 : 3 + 17 + 4 = 4 : 24 = 1 : 6

How many quarters in seven and a half?
OK, so you do 7x4 (seven is the main number, and 4 quarters are a whole). The answer to 7x4 is 28. Then in a half there are 2 quarters, so you add 2 to 28 which is 30

What set of 12 numbers has the following landmarks minimum 28 maximum 34 mode 29 median 30?
You are given the minimum 28 and maximum 34, which means that all the numbers are in the set (28, 29, 30, 31, 32, 33, 34). Since there are fewer than 12 numbers in the set to choose from, there will have to be repeats. You are given the mode 29, which means that 29 appears more often than any other number in the set. The median is 30, which means that half the numbers are above 30 and half are below. There are many different ways to construct a set meeting those conditions. One such set would be (28, 29, 29, 29, 29, 30, 30, 31, 32, 33, 34, 34).
