Convert 8.132132132 ... to a rational expression in the form of a over b , where b ≠ 0.
bezimeni [28]

Let <em>x</em> = 8.132132132...

Then 1000<em>x</em> = 8132.132132132...

Subtract <em>x</em> from 1000<em>x</em> to eliminate the fractional part:

1000<em>x</em> - <em>x</em> = 8132.132132132... - 8.132132132...

999<em>x</em> = 8132 - 8 = 8124

<em>x</em> = 8124/999 = 2708/333

Darcy bought 1 2 pound of cheese and 5 6 pound of hamburger for a barbecue. Use the numbers to compare the amounts of cheese and
Zepler [3.9K]

Answer:

  • Darcy bought more Hamburgers than Cheese
  • 1/2 pound of cheese < 5/6 pounds of Hamburgers

Step-by-step explanation:

Darcy bought 1/2 pounds of cheese and 5/6 pounds of hamburgers.

Convert these to decimals to be sure which is larger:

= 1/2                                                               = 5/6

= 0.5 pounds                                                 = 0.83 pounds

The hamburgers are therefore more so the comparison would look like:

1/2 pound of cheese < 5/6 pounds of hamburgers
