The answer would be 7 right?
Right.
Yay! Thanx soooo much! <3
You're welcome.
To evaluate the expression 3 1/9 * 2 1/4, we need to convert the mixed numbers into improper fractions, then multiply the fractions together, and finally simplify the result if possible.
Step 1: Converting Mixed Numbers to Improper Fractions
To convert a mixed number to an improper fraction, multiply the whole number by the denominator of the fraction and add the numerator. Then, keep the same denominator.
For 3 1/9:
whole number * denominator + numerator = 3 * 9 + 1 = 28
So, 3 1/9 as an improper fraction is 28/9.
For 2 1/4:
whole number * denominator + numerator = 2 * 4 + 1 = 9
So, 2 1/4 as an improper fraction is 9/4.
Step 2: Multiply the Fractions
To multiply fractions, multiply the numerators together and multiply the denominators together.
28/9 * 9/4 = (28 * 9) / (9 * 4) = 252/36
Step 3: Simplify the Fraction
To simplify the fraction, we can find the greatest common divisor (GCD) of the numerator and denominator and divide both by it. In this case, the GCD of 252 and 36 is 36.
252/36 ÷ 36/36 = (252 ÷ 36) / (36 ÷ 36) = 7/1 = 7
So, 3 1/9 * 2 1/4 is equal to 7.
