Q. Without dividing, determine if 2020,035035 is divisible by 99 and explain how you know.\newline20,035 divisible by 920,035 \square \text { divisible by } 9
  1. Calculate sum of digits: Calculate the sum of the digits of 20,03520,035. \newline2+0+0+3+5=102 + 0 + 0 + 3 + 5 = 10
  2. Check divisibility by 99: Determine if the sum of the digits, which is 1010, is divisible by 99.\newlineSince 1010 is not divisible by 99, 20,03520,035 is not divisible by 99.
