Math question: By how much should the number 1930 be increased to become a multiple of 9?

To find the amount by which 1930 should be increased, we need to determine the remainder when 1930 is divided by 9. Dividing 1930 by 9, we get a quotient of 214 with a remainder of 4. Since the remainder is 4, the number 1930 should be increased by 5 to become a multiple of 9. This is because adding 5 to 1930 will give us 1935, which is divisible by 9 (215 × 9 = 1935). Therefore, 1930 needs to be increased by 5 to become a multiple of 9.

Math question: What is the largest prime factor of the number 1930?

To find the largest prime factor of 1930, we start by dividing it by the smallest prime number, 2. After dividing, we get 965.5, which is not a whole number. We move on to the next prime number, 3. Dividing, we get 643.3, which is also not a whole number. Continuing in this manner, we divide by 5, yielding 386, and then by 7, giving us 55.7143. Next, dividing by 11, we obtain 5.059, and lastly, dividing by 13, we have 0.3885. Since 13 is the largest prime number by which 1930 can be divided, it is the largest prime factor. In conclusion, the largest prime factor of 1930 is 13.

Math question: If the number 1930 is added to a certain number, and then the result is multiplied by 5, what is the final value?

To find the final value, let's represent the certain number as 'x'. Adding 1930 to 'x' gives us (x + 1930). Multiplying this by 5 gives us 5(x + 1930). Expanding, we have 5x + 9650. Therefore, the final value is 5x + 9650.
