ozzi

Answer:

$2\frac{13}{22}$

Step-by-step explanation:

$=\frac{19}{4}\div \frac{11}{6}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$=\frac{19}{4}\times \frac{6}{11}$

$=\frac{19}{2}\times \frac{3}{11}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$=\frac{19\times \:3}{2\times \:11}$

$\mathrm{Multiply\:the\:numbers:}\:19\times \:3=57$

$=\frac{57}{2\times \:11}$

$\mathrm{Multiply\:the\:numbers:}\:2\times \:11=22$

$=\frac{57}{22}$

$=2\frac{13}{22}$

TELEVISIONS in 1999, 68% of households with tv's subscribed to cable tv. if 8,000 more subscribers are added to the number of ho

Art [367]

Let x be the number of households with TV.

So .68x would be the number of households with cable.

If 8000 were added to the above number, it would be equal to 67,600,000.

Thus we have our equation:

.68x + 8000 = 67600000

Solving for x:

.68x = 67592000

x = 99,400,000
