Well, friend, when you add two two-digit numbers together, the sum will always be a two-digit number or a three-digit number, not a four-digit number. It's like mixing different colors on your palette - you'll get a beautiful new shade, but it won't be something completely different. Just keep adding those numbers together and creating something wonderful!
The number is 85.

Divide the two-digit number by the one-digit number. If the remainder is zero then the 2-digit number is a multiple and if not, it is not.
The largest two-digit multiple of 5 is 95. This is because the multiples of 5 within the two-digit range start from 10 and go up to 95, with each multiple increasing by 5. The next multiple, 100, is a three-digit number, so 95 remains the largest two-digit multiple.
The only positive two-digit multiple of 12 and 10 is 60.
