Answer:
A.
Step-by-step explanation:
15x1=15 so 2x as many men 15x2=30 30+ 15 is 45.
Answer:
Number of total bees = 400
Step-by-step explanation:
He catches 100 bees from the hive and marks each one with a dye.
He later catches 60 and 15 were marked with the dye.
Its very to estimate from the data given.
I'll answer it with ratio.
We'll ratio number of bees with dye to total he caught the second day.
I.e 15:60 = 1:4
We'll multiply this ratio with the number he caught the first day to know the total.
1/4x =100
X = 100*4
X= 400
Where x is the total number of bees in the bee hive.
To get the distance between
and
, we subtract
from 
That is,

We change the mixed number to improper fraction now to get,

This is the same as,

We collect LCM to be 4

This gives us,


Convert back to mixed number to get,

Therefore the distance between the two numbers is 
Note that the other way round will result in negative value. That is subtracting 6 from
will give 
But since this is distance we find the absolute value and get the same result.
