I only know 40
there are 7 spaces and there are 4 odd and three even spaces.
it is asking what is the probably of not landing on an odd.
there are 4 odds and the rest are even.
so the it is 3 spaces out of 7

it is J 3 over 7

I am not sure the answer for 39 but #40 is J

The question is asking you what fraction of the spinner show the arrow that will NOT land of odd #s. the circle is cut into 7, there is only 3 #s that are not odd. 7 is the denominator and 3 is the numerator

I am sorry that my explaination might confuse you
Hope this help:) :P

Answer:

C. 0.492

Step-by-step explanation:

All I did was add the two numbers. Add them like normal, even though they are in decimal form. You could also use a calculator. If you don't have one, there should be one programed into your phone and computer.

0.467

+ 0.025

= 0.492

I hope this helps! Please let me know if you have any more questions or need any more help. Have a great day!

Answer:

The second option (see attached image)

Step-by-step explanation:

You are looking for a box diagram that represents 9 units, and from those, clearly marked sections that contain 3/2 = 1.5 units.The idea is to count how many 1.5 units you have in 9 units.

The in the second diagram you see 9 boxes subdivided in half. Then outlined in red other smaller boxes of length 1.5 units. We can clearly see from the diagram that there are exactly 6 of these smaller 1.5 units red boxes to produce the total 9 unit object.
