How do you convert 42/16 to a mixed number?

1. 2 5/8

2. 7 9/26

3. 8 25/56

4. 9 1/6

The correct answer is: 2 5/8

To convert the fraction 42/16 to a mixed number, you first divide the numerator (42) by the denominator (16). When you perform the division, 42 divided by 16 equals 2 with a remainder. The 2 represents the whole number part of the mixed number. To find the remainder, you would calculate 42 - (16 times 2), which equals 10. This means you have 10 left over from the division. Next, you take the remainder (10) and put it over the original denominator (16) to form the fractional part of the mixed number. Thus, you get 10/16, which can be simplified by finding the greatest common divisor (GCD) of 10 and 16, which is 2. This simplifies 10/16 to 5/8. As a result, you combine the whole number part (2) with the simplified fraction (5/8) to get the mixed number 2 5/8. This makes the choice A (2 5/8) the correct answer.
