WebInstead, it gives you the remainder after the first number is divided by the second number. In this case, when you divide 10 by 3, the remainder is 1. Essentially, if the remainder has a decimal attached to it, it is given the value 1 If the numbers divide evenly into each other, it is given the value of 0 Like in this example: whats_left_over ...

WebDigital divide in South Africa. The digital divide is described as the characterization of the gap between individuals or countries that have access to technology and individuals or countries that do not. [1] This also includes, but is not limited to: access to computers, internet, and information literacy. WebThe divisibility rule of 7 states that if we multiply the units place digit of the number by 2, and then if the difference between that number and the rest of the number to the left is divisible by 7, then the number is also divisible by 7. For example, let us check whether the number 3437 is divisible by 7 or not. story foldable
number theory - Divisibility by 7. - Mathematics Stack Exchange
WebIf you double the last digit and subtract it from the rest of the number and the answer is: 0, or divisible by 7 then the number itself is divisible by 7. Example: 672 (Double 2 is 4, … WebSuppose we have n which is divisible by 7 and we want to prove it, write it in the form n = 10 k + j so j. Notice that j is the last digit in the decimal expansion. Now here's the trick, because 7 n we know 7 ( n − 21 j) so 7 10 ( k − 2 j). 10 and 7 are relatively prime so we get that 7 ( k − 2 j). Web13 feb. 2024 · As above, a number divisible by 5 and 7 will also be divisible by the LCM of 5 and 7, i.e., 35. The trap answer is 70. Per prime factorization, in order to be sure the number were divisible by 70, we would need to know that integer n also had a factor of 2: (5*7*2) = 70. The prompt doesn't indicate that there is a factor of 2. Answer C ross oyen
