2 7/9x2/3 please help

Furkat [3]

Answer:

Improper: 2 42/9 proper: 6 6/9

Step-by-step explanation:

2 7/9 x 2/3

find the common denominator which is 9 so now we have,

2 7/9 x 2/9

find the numerator which is,

2 7/9 x 6/9

multiply

2 42/9

This fraction is improper so lets make it proper,

42 goes into 9 four times

so we have,

6/9 + 2 + 4

final answer,

6 6/9

How many plastic cubes can fit into the box?

netineya [11]

Option D:

160 plastic cubes can fit into the box.

Solution:

Convert mixed fraction into improper fraction.

Length of the box = 4 ft

Width of the box = $2\frac{1}{2}=\frac{5}{2}$ ft

Height of the box = 2 ft

Volume of the box = length × width × height

$$=4\times\frac{5}{2} \times2$

= 20 ft³

Volume of the box = 20 ft³

Length of the plastic cube = $\frac{1}{2}$ ft

Volume of the cube = length × length × length

$$=\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2}$

$$=\frac{1}{8} \ \text{ft}^3$

Volume of the cube = 0.125 ft³

$$\text{Number of plastic cubes}=\frac{\text{Volume of box}}{\text{Volume of cube}}$

$$=\frac{20}{0.125}$

= 160

Number of plastic cubes = 160

Hence 160 plastic cubes can fit into the box.

Option D is the correct answer.

Which number can be added to rational number to explain that the sum of two rational numbers is rational

Aleks [24]

Answer:

Another rational number

Step-by-step explanation:

Here, we want to get the type of number that should be added to a rational number to explain that the sum of two rational numbers is rational

What we simply have to do here is to add another rational number to the rational number we have already

By adding another rational number to the rational number we have, we will get another rational number

That has successfully proven what we are trying to prove
