If a = 0.6 repeating and b = 0.75, then a x b = blank and a/b = blank

atroni [7]

Answer:

a*b = 1/2

a/ b = 8/9

Step-by-step explanation:

a = 0.66666 and b = 0.75

To multiply it we write the decimal numbers in fraction form

a= 0.666666...

Multiply by 10 on both sides

10 a = 6.66666...

a = 0.66666...

Subtract the second equation

9a = 6

divide by 9 on both sides

$a=\frac{6}{9}=\frac{2}{3}$

so 0.6666 = 2/3

Now we convert 0.75 into fraction form

$0.75=\frac{0.75}{1}$

Multiply top and bottom by 100 to remove decimal

$\frac{75}{100} = \frac{3}{4}$

so 0.75 is 3/4

a= 2/3 and b = 3/4

$a*b = \frac{2}{3} * \frac{3}{4} = \frac{6}{12} = \frac{1}{2}$

$\frac{a}{b} = \frac{\frac{2}{3}}{\frac{3}{4}} = \frac{2}{3} * \frac{4}{3} =\frac{8}{9}$

Factor 36x^2 + 11x-12 please hurry

xz_007 [3.2K]

Answer:

The answer is

Step-by-step explanation:

36x² + 11x - 12

To factor the expression rewrite 11x as a difference

That's

36x² + 27x - 16x - 12

<u>Factor out 9x from the expression</u>

9x( 4x + 3) - 16x - 12

<u>Factor out - 4 from the expression</u>

9x( 4x + 3) - 4( 4x + 3)

Factor out 4x + 3 from the expression

We have the final answer as

Hope this helps you

Svetradugi [14.3K]

Answer:

Step-by-step explanation:

6 / .5 (same as 1/2)

or 6 X $\frac{2}{1} = 12$

Remember when we divide by a fraction we do the following

Keep it (the first number stays the same)

Change it (convert from a division problem to a multiplication problem)

Flip it (flip the fraction that we are dividing by over - this is called a reciprocal)
