a. 11/20 * 100% =

b. The difference between 100% and the % cal. in "a".

To solve these word problems, we will use fractions and convert them into percentages.

(a) To find out what percentage of the marathon Tracy completed, we need to convert the fraction 11/20 into a percentage.

Step 1: Divide the numerator (11) by the denominator (20).
11 ÷ 20 = 0.55

Step 2: Multiply the result by 100 to convert it into a percentage.
0.55 × 100 = 55

Therefore, Tracy completed 55% of the marathon.

(b) To find out what percentage of the marathon Tracy did not complete, we can subtract the percentage she completed (55%) from 100%.

Step 1: Subtract the percentage completed (55%) from 100%.
100% - 55% = 45%

Therefore, Tracy did not complete 45% of the marathon.

So, Tracy completed 55% of the marathon and did not complete 45% of the marathon.
