Answer:
2.09<2.1
Step-by-step explanation:
2.09 < 2.1
Take one number and subtract the other.
If you get a positive, then the first number is larger. If you get a negative, then the second number is larger.
I think 2.1 is larger
2.1
-2.09
-------------
Borrow from the 1
2. 0 10
-2. 0 9
---------------
0. 0 1
Since this is positive, 2.1 is larger
Answer:
first number = 78
second number = 72
third number = 156
Step-by-step explanation:
first number = a
second number = b
third number = c
we have
b=a-6 equation 1
c=2a equation 2
a+b+c=306 equation 3
using equation 1 and equation 2 in equation 3 we have
a+a-6+2a=306
4a=306+6
4a=312
a=312/4
a=78= first number
b=78-6=72=second number
c=2*(78)=156 third number
If you write .6 and .7 as fractions you get 6/10 and 7/10. If you double those you get 12/20 and 14/20, so one potential fraction between the two could be 13/20.
