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:
Divide: 2 : 1
8
= 2
1
· 8
1
= 2 · 8
1 · 1
= 16
1
= 16
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1
8
is 8
1
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
In words - two divided by one eighth = sixteen.
SO FINAL ANSWER IS 16!!! HOPE THIS HELPS YOU mark me the brainliest if im correct
