Question

When a mixed number is converted to an improper fracrtion, the new numerator is placed over the old denominator
a)true
b)false

Answer 1

Answer: a) True

Step-by-step explanation:

When converting a mixed number to an improper fraction, we first multiply the whole number by the denominator of the fraction part and then add the numerator of the fraction part to get the new numerator.

For example, to turn $2\frac{1}{3}$ to an improper fraction, we would first multiply 2 (the whole number) by 3 (the denominator) and then add the numerator to get the new numerator. The improper fraction would be $\frac{7}{3}$.

The denominator remains the same. So, the new numerator is simply placed over the old denominator.
