2/6 < ?select the three fractions that make this comparison true

3/6
2/8
2/4
2/3
1/6

Answers

3/6 . . . . .
Yes.  2 of anything is less than 3 of the same thing ... like sixths. 

2/8 . . . . .
No.  When changed to common denominator, the inequality
would say
                            8/24 <  6/24
and that's not true.

2/4 . . . . .
Yes.  When changed to common denominator,
the inequality would say
                                    4/12 <  6/12
and that's true.

2/3 . . . . .
Yes.  When changed to common denominator,
the inequality would say
                                    2/6 <  4/6
and that's true.

1/6 . . . . .
No.  2 of anything is more than 1 of the same thing ... like sixths.    


2/6 is less than 3/6, 2/4 and 2/3 because  is equvalant to 1/3 and the followings are all greater than 2/6-> 1/3

Hello,

As 4²+(5/2)²=22.25=89/4 (Pytagorean theorem)
Perimeter of the triangle =2*√89 /2 +5 =5+√89
Lateral area: 18*(5+√89)
Total area= 90+18√89+ 4*5/2 *2 =110+18√89 ≈279.811..(ft²)

If two squirrels live in one square meter of a fifty square meter park what is the park's estimated squirrel population?

Answers

Well let's find our key words : There are two squirrels that live in one square meter in a park and there are fifty square meters in total. That means multiply : 50•2. I do that because there are 50 square meters and two squirrels per meter. 50•2=100. The total parks estimated squirrel population is 100. :) Hoped I helped! 
2 x 50 = 100
es. the population is 100 in the park
