The properties are listed in the following order:

Given
Conversion from mixed numbers into rational numbers / Associative property
Addition of fractions with different denominators
Mutiplication of fractions
Associative property / Existence of multiplicative inverse / Modulative property / Definition of division

<h3>How to simplify a product of rational numbers</h3>

Herein we are in front of a product of three rational numbers, that is, numbers of the form m / n, where m, n are integers and n ≠ 0. We need to apply definition and theorems from algebra to simplify a given number, whose procedure is shown in detail:

(2 3 / 4) · (1 1 / 8) · 32 Given

(2 + 3 / 4) · (1 + 1 / 8) · 32 Conversion from mixed numbers into rational numbers

(11 / 4) · (9 / 8) · 32 Addition of fractions with different denominators

(99 / 32) · 32 Mutiplication of fractions

99 Associative property / Existence of multiplicative inverse / Modulative property / Definition of division / Result

A keychain-sized Rubik’s Cube® is made up of small cubes. Each small cube has a surface area of 1.5 square inches.

satela [25.4K]

The answer would be 0.5 square inches. This is because the surface area formula of a cube is 6a^2. So divide 1.5 by 6, you get 0.25. Then square root 0.25 and the answer is 0.5 square inches.

Which point is NOT on the line y = 5x + 1?

12345 [234]

To find which point is NOT on the line y = 5x + 1, we just need to plug each point into equation y=5x+1 to see which one point satisfies this equation.

check for (1,6)

y=5x+1

or 6=5*1+1

or 6=5+1

or 6=6

Which is TRUE.

--------

check for (2,11)

y=5x+1

or 11=5*2+1

or 11=10+1

or 11=11

Which is TRUE.

--------

check for (0,1)

y=5x+1

or 1=5*0+1

or 1=0+1

or 1=1

Which is TRUE.

--------

check for (-1,6)

y=5x+1

or 6=5*(-1)+1

or 6=-5+1

or 6=-4

Which is FALSE.

--------

Since only point (-1,6) fails to satisfy the given equation hence point (-1,6) is the final answer.

You've baked 26 cookies, which is two-thirds of all the cookies you planned to bake. How many cookies did you plan to make?

hodyreva [135]

Answer,

(26/2) * 3

= 39

Explanation,

26 cookies is only 2/3 of 3/3. So, we divide 26 by 2 to see how many cookies are in 1/3. We then can find out that when you make 1/3 of the cookies there are 13. Since that is only 1/3 and we want to find out 3/3. We multiply 13 by 3 and get 39 which is all the cookies she planned to make.

Hope this helps :-)
