<span>the line over the 28 means the 28 repeats forever. 1.282828.... and so on let x be the rational number 1.28... we can use this trick: 100*1.282828....= 128.282828... (the decimal 28 part repeats) 100x = 128.28... next: 100x - x = 128.282828... - 1.282828... the .282828... part will be subtracted away 99x = 127 divide both sides by 99 to get x= 127/99</span>

Natalka [10]
Hey there! :) How are you? Basically what you said is right. 

Question 1: There are 16 oz (ounces) in a pound, so we do 64/16= 4 lbs (pounds). 

Question 2: If Jack has 3 pounds of pasta, that would mean he has 48 ounces, since 1 pound is 16 oz, so 16*3= 48 ounces. 

Hoped I helped! Have a nice day, and keep smiling! :)
