1: The product of 3 and 3/11 is 9/11.
Answer: C. 9/11
2: Multiplying 3/16 by 4 gives us (3/16)(4) = 12/16. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 4. So the simplified form is 12/16 ÷ 4/4 = 3/4.
Answer: B. 3/4
3: Multiplying 4/7 by 5 gives us (4/7)(5) = 20/7. To convert this improper fraction to a mixed number, we divide the numerator (20) by the denominator (7) to get the whole number part and the remainder becomes the numerator of the fraction part. So, 20 ÷ 7 = 2 remainder 6. Therefore the answer is 2 6/7.
Answer: D. 2 6/7
4: Lara's answer of 12/39 is not correct. When multiplying a fraction by a whole number, we multiply the numerator of the fraction by the whole number. So, (4/13) * 3 = (4 * 3)/(13) = 12/13.
Answer: D. No, she should have multiplied only the denominator by the whole number.
5: Multiplying 710 by 5 gives us 710(5) = 3550. To write this as a mixed number in simplest form, we divide 3550 by 10 to get the whole number part and the remainder becomes the numerator of the fraction part. So, 3550 ÷ 10 = 355 remainder 0. Therefore the answer is 355 0/10, which simplifies to 355/10 or 35 5/10 or 3 5/10.
Answer: C. 3 5/10
