Answer: The answer for the first question I believe is 1/4 or 25%. The second answer is 2/4, 1/2 which is 50%

Step-by-step explanation:

There are only 4 options to pick from, and 7 is only one option, thus being 1/4 the possibilities. 1/4 as a percentage is 25% multiply 1/4 by 25 to get a denominator of 100, and a numerator of 25, 25 being the percentage. 5, and 6 are the only numbers less than 7. that means there are 2 choices out of 4 that are less that 7. The fraction form would be 2/4, or 1/2 simplified. and then multiply the numerator and denominator by 50 to get an answer of 50/100 or 50%
