What number of spokes do 80 bicycles have if each wheel has 32 spokes and each handlebar has three black, white and yellow decals on them?

5,120 spokes

Step-by-step explanation:

There are 80 bikes and each of them have two wheels.

80 x 2 = 160 wheels

There are 32 spokes per wheel.

32 x 160 = 5,120 spokes

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.
