Step 3: Simplify the fraction
Find the greatest common divisor (GCD) of 196 and 48, which is 4. Simplify :
.
Step 4: Convert to a mixed number
as a mixed number is since 49 divided by 12 is 4 with a remainder of 1.
Therefore, the solution to the problem is .
\( 1:\frac{3}{4}= \)
Mixed numbers represent one complete value, not separate parts. When you multiply , you're multiplying all parts together, which only works correctly with improper fractions.
Use this formula: Improper fraction = (denominator × whole number + numerator) ÷ denominator. For :
Yes! Always check if your fraction can be simplified by finding the GCD. In this problem, simplifies to by dividing both by 4.
Convert back when your improper fraction is larger than 1 (numerator > denominator). Since has 49 > 12, it becomes .
That's normal! When multiplying fractions, you multiply across: numerator × numerator and denominator × denominator. You don't need a common denominator like in addition.
