6 and 3/8
7 and 2/5
combine
you can just add the whole numbers
6+7=13
then add the confusing ones
3/8 +2/5
convert the bottom number to the same number
the number is 40
multiply 3/8 by 5/5=15/40
multiply 2/5 by 8/8=16/40
add
15/40+16/40=31/40
the naswer is 13 and 31/40
Answer:
The distance between the givens points is 9 unit
Step-by-step explanation:
Given points are as :
A = ( 1 , 5 )
B = ( 1 , - 4 )
So, The Distance between points A and B = AB
Now, From Distance formula
AB = 
Or, AB = 
Or, AB = 
Or, AB =
= 9
Hence The distance between the givens points is 9 unit Answer
