Megan's dog Sparky eats 4 1/4 c of food each day. Explain how Megan can determine how much food to give Sparky if she needs to feed him only 2/3 as much. Solve the problem.
Tornyn T.Z., your wrong. The math term "as much" means you divide. In 4 1/4, multiply the whole number 4 by the denominator which is in this case 4. 4 x 4 = 16, so we get a improper fraction of 16/4. To find the numerator when this mixed number is shown as an improper fraction, use addition. 16/4 + 1/4 is 17/4. Find the inverse of 2/3 by swapping the numerator and denominator to get 3/2. Multiply the numerators and denominators. 17/4 x 3/2 = 51/8. 51 divided by 8 is 6 with the remainder of 3. The remainder is now the numerator, so we get a final answer of 6 3/8.
However, 4 1/4 TIMES 2/3 = 2 5/6. 4 1/4 SUBTRACT 2/3 is 3 7/12. 4 1/4 PLUS 2/3 = 4 11/12. But since it said "as much" we divide, and it seemed that other people didn't pick up those two important words. That is why you shouldn't Google up your problem and reply on the answer most people provide, but instead try to figure it out first if you can.
Im confused on the problem can anyone help me? Im in 5th grade
The answer is 2 5/6 because you have to keep 2/3 the same and then you have to make 4 1/4 an improper fraction and then that give you 34/12. It is another improper fraction so then you make it a mixed number. You would get 2 10/12 because 12 goes into 34 two times with 10 leftover. Then you have to simplify because it can be simplified by 2. So your final answer is 2 5/6
