Simplify (-2/5) divided by (8/9) times (2/9) divided by (-1/3) explain and show all steps
spayn [35]

Simplification of (-2/5) divided by (8/9) times (2/9) divided by (-1/3) is 0.3

<em><u>Solution:</u></em>

Given that,

Simplify (-2/5) divided by (8/9) times (2/9) divided by (-1/3)

Here "times" represent multiplication

<em><u>The above sentence can be written mathematically as:</u></em>

\frac{-2}{5} \div \frac{8}{9} \times \frac{2}{9} \div \frac{-1}{3}

Convert the problem to multiplication by changing the division sign to multiplication. When we change division sign to multiplication, the fraction becomes reciprocal

\rightarrow \frac{-2}{5} \times \frac{9}{8} \times \frac{2}{9} \times \frac{3}{-1}

Cancelling the common terms in numerator and denominator,

\rightarrow \frac{-2}{5} \times \frac{1}{8} \times \frac{2}{1} \times \frac{3}{-1}

Multiplying terms in numerator and denominator,

\rightarrow \frac{-12}{-40}

Negative sign in numerator and denominator cancels each other

\rightarrow \frac{-12}{-40} = \frac{12}{40}

Reducing to lowest terms we get,

\rightarrow \frac{12}{40} = \frac{3}{10}

In decimal form we get,

\rightarrow \frac{3}{10} = 0.3

Thus solution to given expression is 0.3

Rina is 6x + 3:8 feet tall and Ryan is 5x + 1/8 feet tall. How much taller is Rina than Ryan?
Dimas [21]

Answer: Rina is x+\dfrac{1}{4} feet taller than Ryan.

Step-by-step explanation:

Given, the height of Rina = 6x+\dfrac{3}{8} feet

The height of Ryan = 5x+\dfrac{1}{8} feet

To find : How much taller is Rina than Ryan?

Clue : Rina is taller than Ryan.

For that , we need to check the difference of the height between Ryan and Rina

i.e. (height of Rina) - (height of Ryan)

=6x+\dfrac{3}{8}-(5x+\dfrac{1}{8})\\\\=6x+\dfrac{3}{8}-5x-\dfrac{1}{8}\\\\=x+\dfrac{3-1}{8}\\\\=x+\dfrac{2}{8}\\\\=x+\dfrac{1}{4}

Hence, Rina is x+\dfrac{1}{4} feet taller than Ryan.
