Question 473407
Not sure how you came up with your answer?
First convert each mixed number to an improper fraction.
Step 1: Multiply denominator by whole number
Step 2: Add product to numerator, the result will be the new numerator and denominator does not change
Rewritten as improper fractions:
{{{(9/2) - (7/2)}}}
Since they share the same denominator of 2, just subtract the numerators
{{{(9-7)/2 = 2/2 = 1}}}
Answer is 1
