Tangerine is simply color orange, which is an addition of red and yellow colors. To analyze if the portions written below are reasonable, the given sum must equal to the sum of the individual red and yellow parts.
Total Red + Total Yellow = 5(3/10) 3(9/10) + 2(3/8) ? 5(3/10 3.45 ? 1.5 3.45 ≠ 1.5
<em>Since they are not equal, then it means the portions are unreasonable.</em>
