Ranjit wants to measure the length of a table, but has no ruler or tape measure. Using what he has at hand, he finds that the table is
about as long as 6 unsharpened pencils laid tip to tip. If each
unsharpened pencil measures 18 centimeters in length, what is the
length of the table, in centimeters?

  108 cm

Step-by-step explanation:

6 pencil-lengths will be ...

  6 × 18 cm = 108 cm

The length of the table is 108 cm.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
