How do you solve 7 divided by 3?
Answer and Explanation: 7 divided by 3 is 2 with a remainder of 1.
By using mental math, you start by looking at the number 7..
Which number is divisible by?
In math, a number is said to be divisible by another number if the remainder is 0. Divisibility rules are a set of general rules that are often used to determine whether or not a number is evenly divisible by another number. 2: If the number is even or end in 0,2,4, 6 or 8, it is divisible by 2.
What is the divisibility rule of 7 and 11?
Rule: Take the last digit and cross it out from the original number. Then double it. Subtract it from the “new” number which is the original number excluding the last digit. If the difference is divisible by 7, then the original number must also be divisible by 7.
What number divided by 7 and is 7?
49Therefore, the answer to what divided by 7 equals 7 is 49. You can prove this by taking 49 and dividing it by 7, and you will see that the answer is 7.
What are the 3 digit numbers divisible by 7?
∴ There are 128 3-digits number which are divisible by 7.
Is 29 divisible by any number?
The numbers that 29 is divisible by are 1 and 29 and 29. You may also be interested to know that all the numbers that 29 is divisible by are also known as the factors of 29. Not only that, but all the numbers that are divisible by 29 are the divisors of 29.
What is the divisibility rule of 7 with example?
Divisibility rules for numbers 1–30DivisorDivisibility conditionExamples7Subtracting 2 times the last digit from the rest gives a multiple of 7. (Works because 21 is divisible by 7.)483: 48 − (3 × 2) = 42 = 7 × 6.Subtracting 9 times the last digit from the rest gives a multiple of 7.483: 48 − (3 × 9) = 21 = 7 × 3.65 more rows
Who invented divisibility rule of 7?
Chika OfiliChika Ofili, who is based in the UK, was awarded over the weekend at the TruLittle Hero Awards for discovering the new formula for divisibility by seven in mathematics.
When a number is divided by 7 its remainder is?
Properties of Remainder: The remainder is always less than the divisor. If the remainder is greater than the divisor, it means that the division is incomplete. It can be greater than or lesser than the quotient. For example; when 41 is divided by 7, the quotient is 5 and the remainder is 6.
What are the numbers divisible by 6?
Divisible by 6 is discussed below: A number is divisible by 6 if it is divisible by 2 and 3 both. Consider the following numbers which are divisible by 6, using the test of divisibility by 6: 42, 144, 180, 258, 156.
Can odd numbers be divided 4?
This means that the number is ODD and 2 will not divide into it evenly. There will be a remainder. So 34,807 is not divisible by 2. The Rule for 4 : If the last two digits of a whole number are divisible by 4, then the entire number is divisible by 4.
Why does divisibility rule for 7 work?
Divisibility by 7: The absolute difference between twice the units digit and the number formed by the rest of the digits must be divisible by 7 7 7 (this process can be repeated for many times until we arrive at a sufficiently small number).
What divided by 6 gives you 7?
42In other words, you have an unknown number (X), and then if you divide that X by 6 you get 7. Then what is that X? Therefore, the answer to what divided by 6 equals 7 is 42. You can prove this by taking 42 and dividing it by 6, and you will see that the answer is 7.
How do you divide by 7?
Dividing by 7Take the last digit in a number.Double and subtract the last digit in your number from the rest of the digits.Repeat the process for larger numbers.Example: Take 357. Double the 7 to get 14. Subtract 14 from 35 to get 21, which is divisible by 7, and we can now say that 357 is divisible by 7.
What are the numbers divisible by 11?
If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728. Similarly, for 31415, the alternating sum of digits is 3 – 1 + 4 – 1 + 5 = 10.
