Answer:
5/2 = 2 1/2 = 2.5
Step-by-step explanation:
4 * 5/8 = 4/1 * 5/8 = (5 * 4)/(1 * 8) = 20/8 = 5/2 = 2 1/2 = 2.5
Let's find the decimal value of each letter choice.
Choice A: This choice is already in decimal value.
Choice B: To turn this into a decimal, divide this by 100%. You get 0.4. This matches with choice A.
Choice C: To turn this into a decimal, divide this by 100%. You get 0.04. This does not match with A and B.
Choice D: 2/5 can be turned into 40/100. 40/100 can be converted into the decimal of 0.4. This matches with choices A and B.
Thus, the only different answer choice is C. That's your answer. I hope this helps! :)
The interval notation is used to report domains and ranges. It uses brackets and parentheses. Brackets are used if the solution includes the point on the curve. In other words, this is used when the inequality has the ≤ or ≥ symbol. Parentheses are used if the inequality symbols are just < or >. It means that the solution does not include the points on the curve, but on the data points that are greater or lower. For example, if the domain is 2<x≤8, the inerval is written as: (2,8].
12 1/2 because you do 5/6 x 15/1 which 6/3 equals 2 and 15/3 equals 5 so you do 5/2 x 5/1
