Answer:

\frac{12}{27} Simplified version

Step-by-step explanation:

(\frac{4}{5} + \frac{1}{3}) × \frac{5}{9}

The first step would be to add together what is in the parenthesis. Make sure that both fractions have the same denominator. In this problem they don't, so we have to find the least common number that they both have. The number here would be 15. 5 × 3 = 15 and vise versa.

((\frac{4}{5} x \frac{3}{3}) + (\frac{1}{3} x \frac{5}{5})) × \frac{5}{9}

(\frac{12}{15} + \frac{5}{15}) × \frac{5}{9}

(\frac{17}{15} × \frac{5}{9} Multiply straight across (denominators do <u>NOT</u> need to be the same)

\frac{85}{135} = \frac{12}{27}

T&amp;L - Math 7 - Volume 7.4 -19-20
Mashcka [7]

Answer: You would need 512 cubic centimetres

Step-by-step explanation: The first approach to this question would be to understand the properties of the shape given in the question.

If a cube has an edge with length 8 cm, then all edges measure 8 cm as well. That is one property of a cube. Hence, the length, width and height all measure 8 cm each.

The volume of a cube is given as follows;

V = L x W x H (and the answer is expressed as V³)

Since the length , width and height all measure 8 cm, the volume can simply be expressed as

V = L x L x L

V = L³

V = 8³

V = 512 cm³

Therefore to completely fill a cube with edge length of 8 cm you would need 512 cubic centimetres.
