Answer:
Step-by-step explanation:
From the first set 20 corresponds to 1/6
for a fraction of 2/3 = 4/6
thus 4 * 1/6 = 4 * 20 = 80 calories
For 10 calories,
20 * 1/2 = 10 calories thus
1/6 * 1/2 = 1/12
For 90 calories,
10 * 9 = 90 calories thus,
1/12 * 9 = 9/12 = 3/4
Answer: The answer is A
Step-by-step explanation:
We know there are 12 months in a year so we would multiply 1 1/4 by 12. We can write 1 1/4 as 1.25 (to make it easier to multiply). 12x1.25=15
Your answer is 15 vacation days in one year
