how to use hundreds chart to answer this;(1)what % of the numbers are multiples of 3 (2)what % of the numbers are multiples of both 2 and 3 (3) what% of the numbers are factors of 100 (4)what % of the numbers are prime numbers? i really have no idea how to use hundreds chart to answer this questions,so please explain.thanks
To use a hundreds chart to answer these questions, you will need a printed or digital copy of a hundreds chart. A hundreds chart is a grid of numbers from 1 to 100, usually arranged in rows and columns. Each number on the chart represents a single cell.
1) What % of the numbers are multiples of 3:
Start by scanning the chart and looking for numbers that are divisible by 3. You can do this by identifying numbers that have a remainder of 0 when divided by 3. Count the total number of these numbers and divide it by 100 (the total number of cells in the chart). Finally, multiply the result by 100 to find the percentage. For example, if there are 30 multiples of 3, the calculation would be (30/100) x 100 = 30%. Therefore, 30% of the numbers on the hundreds chart are multiples of 3.
2) What % of the numbers are multiples of both 2 and 3:
To find numbers that are multiples of both 2 and 3, you need to identify numbers that have a common multiple of 6. These numbers can be found at the intersection of the rows and columns that represent multiples of 2 and 3. Count the total number of these numbers and follow the same steps as in question 1 to calculate the percentage.
3) What % of the numbers are factors of 100:
To find numbers that are factors of 100, you need to identify numbers that divide evenly into 100 without a remainder. These numbers can be found by identifying numbers that have a common multiple of 1, 2, 4, 5, 10, 20, 25, 50, or 100. Count the total number of these numbers and follow the same steps as in question 1 to calculate the percentage.
4) What % of the numbers are prime numbers:
To find prime numbers, you will need to understand the concept of prime numbers. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself. To determine whether a number is prime or not, you can scan the hundreds chart and mark which numbers are prime. Count the total number of prime numbers and follow the same steps as in question 1 to calculate the percentage.
Remember, a hundreds chart is a helpful visual tool for understanding number patterns and relationships. To answer these questions accurately, you may need to use additional mathematical knowledge and concepts.
