To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Convert mixed numbers to improper fractions:
For :
Multiply the whole number 4 by the denominator 3 and add the numerator 2:
.
Thus, .
For :
Multiply the whole number 1 by the denominator 5 and add the numerator 1:
.
Thus, .
Step 2: Multiply the improper fractions and :
.
Step 3: Simplify the resulting fraction and convert it to a mixed number if necessary:
Find the greatest common divisor (GCD) of 84 and 15, which is 3.
Divide both numerator and denominator by their GCD:
.
Convert the improper fraction to a mixed number:
Divide 28 by 5: Quotient is 5, remainder is 3.
Thus, .
Therefore, the solution to the problem is .
\( 1\frac{4}{5}\times1\frac{1}{3}= \)
Because mixed numbers represent one complete value, not separate parts! means 4 plus , so you must convert to improper fractions first to get the correct product.
Use this memory trick: "Multiply, then Add, Keep the bottom" - Multiply whole number × denominator, add the numerator, keep the same denominator!
That's okay! Not all fractions can be simplified. Just make sure you've checked for common factors between numerator and denominator. If there aren't any, your answer is already in simplest form.
It depends on what the problem asks for! If the answer choices are mixed numbers (like in this problem), then yes. If they're improper fractions, you can leave your answer as .
Start by checking if both numbers are divisible by small primes like 2, 3, 5. For 84 and 15: both divide by 3, giving us .
Learning the steps is more important than the final answer! Practice by hand first to understand the process, then you can use a calculator to check your work.
