What strategy can you use to determine if a two digit number is a multiple of a one digit number?
Begin by drawing the area model box. Since our largest number is two digits, we will need to divide it into two columns. Divide it into a tens section (which should be larger to fit the larger product) and a ones section. Since the other number in the problem is one digit, we only need one row.
How do you multiply a two digit number by a one digit number?
This method is known as vertical method.
- Write the bigger number.
- Give the multiplication sign (x).
- Write the 2nd number.
- Multiply the 2nd number by the digit in ones place and write the answer.
- Multiply the tens number by the 2nd number and write the answer using tens.
How many 2-digit numbers are there?
The total number of two digit numbers is 90. From 1 to 99 there are 99 numbers, out of which there are 9 one-digit numbers, i.e., 1, 2, 3, 4, 5, 6, 7, 8 and 9. If one digit numbers are subtracted from 99 we get 90 two-digit numbers.
How to tell if a number is a multiple of 2 2?
So, to tell if any number is a multiple of 2 2 look at the last digit. If it is 0,2,4,6,or 8 0, 2, 4, 6, or 8, then the number is a multiple of 2 2.
How to check if a number is divisible by two?
Since the last digit is a 4, this is an even number and therefore divisible by 2. Check if any number is divisible by two. Type in any number that you want, and the calculator will use the rule for divisibility by 2 to explain the result. See what the rule for divisibility by two has to say about the following number:
Which is the product of two counting numbers?
The numbers 2,4,6,8,10,12 2, 4, 6, 8, 10, 12 are called multiples of 2 2. Multiples of 2 2 can be written as the product of a counting number and 2 2. The first six multiples of 2 2 are given below. A multiple of a number is the product of the number and a counting number. So a multiple of 3 3 would be the product of a counting number and 3 3.
Which is a multiple of a counting number?
A multiple of a number is the product of the number and a counting number. So a multiple of 3 3 would be the product of a counting number and 3 3. Below are the first six multiples of 3 3. We can find the multiples of any number by continuing this process.
