What is the reciprocal of each mixed number? (drag and drop homework)
kolezko [41]
In order to solve this, you need to make these irregular fractions. So, take the integers, 4, 5, and 1, and multiply them by the denominator, 6(Make sure to keep the denominator below them). You should now have 24/6, 30/6, and 6/6. Next, add each number to it’s corresponding fraction. You should now have 25/6, 35/6, and 11/6. Finally, just reverse them!
A 4 1/6—> 3. 6/25
B 5 5/6—> 4. 6/35
C 1 1/6 —> 1. 6/11
