Step-by-step explanation:

The ratio of the length and the breadth of rectangle=2:1

Let length be 2x, then breadth = x

Now,

Length(l)=12 m

or,2x=12m

or,x=6m

x=breadth=6m

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

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

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

Somebody help me!

tiny-mole [99]

Answer:

josh vendió 17 libros recaudando 306 dolares .

jessica vendió 255 libros recaudando 4590 dolares.

Step-by-step explanation:

Sustituimos por variables :

libros que vendió Jessica = x

libros que vendió Josh = y

entonces:

x + y = 272

Jessica vendió 15 veces mas libros que josh:

x = 15y

Reemplazamos en la anteriior ecuacion:

15y +y = 272

16y = 272

y = 17

Reemplazamos en la primela ecuacion :

x + 17 = 272

x = 255
