Question

What is the combined weight of all the kittens? Weight of kittens: 1/4 pound: 2 kittens. 3/8 pound: 3 kittens. 1/2 pound: 3 kittens. 5/8 pound: 3 kittens

Answer 1

Answer:

The combined weight of all the kittens is 5 pounds.

Step-by-step explanation:

The distribution of kittens according to their weights is as follows:

Weight (W)       No. of Kittens (f)

  $\frac{1}{4}$ pounds                  2

  $\frac{3}{8}$ pounds                  3

  $\frac{1}{2}$ pounds                  3

  $\frac{5}{8}$ pounds                  3

Compute the combined weight of all kittens as follows:

Total weight = ∑ (W × f)

                     $=(\frac{1}{4}\times 2)+(\frac{3}{8}\times 3)+(\frac{1}{2}\times 3)+(\frac{5}{8}\times 3)$

                     $=\frac{1}{2}+\frac{9}{8}+\frac{3}{2}+\frac{15}{8}$

                     $=\frac{4+9+12+15}{8}$

                     $=\frac{40}{8}$

                     $=5$

Thus, the combined weight of all the kittens is 5 pounds.
