Mr. Henry has 9 rocks in his collection. Each rock weighs 4/3 pounds. Is the total weight of the 9 rocks greater than, less than, or equal to 9 pounds?

Answer 1

9 rocks * 4/3 pounds/rock = 12 pounds, which is greater than 9 pounds

Answer 2

To begin, multiply 4/3 by 9. 36/3. Since a fraction is also a division problem, you can divide 36 by 3 to determine whether the total weight is greater than,less than, or equal to nine pounds. Hope this helps out. Teacher Bobby

Answer 3

In addition to what others shared, you can also use number sense to logically solve the answer without multiplication:

1. You know each rock is 4/3lbs.
2. You know 4/3 is greater than 1lb.
3. If you have 9 rocks, they will have to weigh greater than 9 lbs.
4. The total weight is greater than 9lbs.

Mathematically, as others shared:

1. You write your equation 9 x 4/3
2. 9 is a whole number that you convert to the improper fraction of 9/1. Now you have 9/1 x 4/3
3. Any whole number can be easily converted into an improper fraction of equivalent value by using 1 as the denominator.
4. To multiply fractions, you multiply numerators (9 x 4 = 36) and denominators (1 x 3 = 3) together.
5. Your new fraction is 36/3, which is the same as 36 divided by 3 and reduces to 12.
6. 12lbs > 9lbs

Answer 4

Mr. Henry has 9 rocks in his collection. Each rock weighs 4/3 pounds. Is the total weight of the 9 rocks greater than, less than, or equal to 9 pounds?

To figure out this answer, multiply 4/3 by 9. This would be 36/3. Since a fraction is also a division problem, you can divide 36 by 3 to determine whether the total weight is greater than,less than, or equal to nine pounds.

Answer 5

Hello Ceasar,

To find the solution this math problem, multiply 4/3 x 9.

To do that: convert the whole number 9 to the improper fraction of 9/1, and multiply 9/1 x 4/3 = 36/3 = 12 (pounds).

Therefore, the answer to your questions is, yes, the total weight of the 9 rocks is greater than 9 pounds.
