Final answer:
To subtract 94 from 42, you borrow from the tens place value and subtract. The result is -52, which can be written as -26 as a mixed number.
Step-by-step explanation:
To subtract 94 from 42, you start by subtracting the ones place value. Since 4 is less than 4, you need to borrow from the tens place value, making it 3. Then subtract 4 from 14, which equals 10. Finally, subtract the tens place value, which is 4, from 3, resulting in -1. So 94 - 42 is equal to -52.
To write this as a mixed number, you divide the negative value by the denominator, which is 2. The quotient is -26, with a remainder of 0. Therefore, -52 can be written as -26 as a mixed number.
