How many time more respondents chose either black or silver than red round to the nearest tenth if necessary

Silver = 0.2

Black = 0.14

Red = 0.09

In this question you are asked to compare "either black or silver" with "red" and allowed to round up to the nearest tenth. Silver is already rounded to tenth. If you round the black and red then

Silver = 0.2

Black = 0.1 - - - > round down because the 0.04 value is 4, which was lower than 5

Red = 0.1 - - >round up because the 0.09 value is 9, which was higher than 5

The word 'either black or silver" mean that combination of the frequency. Then the equation should be: black + silver = 0.1 + 0.2 = 0.3

If you compare it with red, then: 0.3 / red = 0.3 / 0.1 = 3 times more
