The sum of 67 and 78 is 145.
It is a mathematical statement, which can be converted to an equation and then solved.
78 + 85 = 163
To determine if 78 is a multiple of 3, we can use the divisibility rule for 3. The rule states that if the sum of the digits of a number is divisible by 3, then the number itself is also divisible by 3. In this case, 7 + 8 = 15, which is divisible by 3. Therefore, 78 is indeed a multiple of 3.
How about: 11+67 = 78
