What is the sum of the digits of the number 388?

The number 388 can be broken down as 3 + 8 + 8 = 19. Hence, the sum of the digits is 19.

Math question: If 388 is divided by 4, multiplied by 7, and then subtracted by 29, what is the resulting value?

To find the solution, we first divide 388 by 4, which equals 97. Then we multiply this result by 7, resulting in 679. Finally, subtracting 29 from 679 gives us the final value of 650. Hence, after the given operations, the resulting value for 388 is 650.

Math question: What is the product when 388 is multiplied by its square root and divided by the sum of its digits?

To find the product, we first find the sum of the digits: 3 + 8 + 8 = 19. Then, we calculate the square root of 388, which is approximately 19.6977. Now, dividing 388 by the sum of its digits (19) gives us 20.421, which is the desired product. Therefore, the product is 20.421 when 388 is multiplied by its square root and divided by the sum of its digits.
