Who first recognized that the ratio of the number of atoms is the same as the ratio of the masses that combine?
The first person to recognize the total ratio of the number atoms is the same as the total ratio of the ratio of the mass is JOHN DALTON.This is also called the "Law of Multiple Proportion"
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 blue counters must be added so that the ratio of yellow counters to total counters is 16?
To determine how many blue counters must be added so that the ratio of yellow counters to total counters is 16, you need to set up the equation based on the current number of yellow counters (Y) and the current number of blue counters (B). Let X be the number of blue counters added. The equation would be ( \frac{Y}{Y + B + X} = \frac{16}{1} ). You can solve for X to find the number of blue counters needed.
What word problem ratios of yellow beads to blue beads is 3 to 2?
In a word problem where the ratio of yellow beads to blue beads is 3 to 2, for every 3 yellow beads, there are 2 blue beads. This ratio can be simplified to 3:2. This means that for every 5 beads in total, 3 are yellow and 2 are blue. To find the actual number of beads, you would need to know the total quantity or be given additional information.
What is the ratio of 4boys and girl's to the children in the family?
To determine the ratio of boys to girls in a family with 4 boys and an unspecified number of girls, we first need the total number of children. If we assume there are ( g ) girls, the total number of children would be ( 4 + g ). The ratio of boys to girls is then ( 4:g ), and the ratio of boys to the total number of children is ( 4:(4 + g) ). Without knowing the number of girls, we cannot provide a specific numerical ratio.
In a given school there are 240 boys and 260 girls. A) What is the ratio of the number of girls to the number of boys B) What is the ratio of the number of boys to the total number of pupils in the sc?
A) The ratio of the number of girls to the number of boys is 260:240, which simplifies to 13:12. B) The total number of pupils in the school is 240 boys + 260 girls = 500 pupils. Therefore, the ratio of the number of boys to the total number of pupils is 240:500, which simplifies to 12:25.
What is crude mortality ratio?
number of deaths by total number of deaths in a population
How do you Calculate the ratio of purines to pyrimidines?
To calculate the ratio of purines to pyrimidines in a nucleic acid sequence, count the number of purine bases (adenine and guanine) and the number of pyrimidine bases (thymine, cytosine, and uracil) in the sequence. Then divide the total number of purines by the total number of pyrimidines to get the ratio.
There are 17 boys and 12 girls in the school jazz band. Find the ratio of the number of girl in the band to the total number of students in the band.?
To find the ratio of the number of girls in the band to the total number of students, first calculate the total number of students: 17 boys + 12 girls = 29 students. The ratio of girls to the total number of students is 12 girls to 29 students, which can be expressed as 12:29.
