Answer:
Step-by-step explanation:
We khow that A is the sum of all odd numbers that are less than 100
So A= 1+3+5+...+99
We can calculate this sum without adding all this numbers one by one
A = the number of terms *( first term + last one ) over 2
To get the number of terms we substract the first term from the last term then we add one
We khow that odd numbers are wiritten this way : 2*n +1 where n is an integer
So 99= 2*49+1
1= 2*0+1
So the number of terms is : 49-0+1 =50
So A= 50*(1+99)/2 = 2500
Foloowing the same method we get :
B= (49-1+1)*(2+98)/2= 2450
A>B
Answer:
53/10, 5 9/25 ; 5.81 ; 5.818
Step-by-step explanation:
To find the solution we need to make some calculations:
53/10 = 5.3
5 9/25 = 5.36
So we have that the solution is:
53/10, 5 9/25 ; 5.81 ; 5.818
