Step-by-step explanation:
Answer:
0.38 and 0.7 maybe it's the answer
Step-by-step explanation:
power of 10 in above questions are 2 and 3 respectively
So even postive integers are by defention in form 2k where k is a natural number so
let the sum of even integers to n=S
S=2(1+2+3+4+5+6+7+8+......+k-1+k
divide bith sides of equation 1 by 2
0.5S=1+2+3+4+5+...........+k-1+k
S=2(k+(k-1)+..............................+2+1)
divide both sides of equation 2 by 2
0.5S=k+k-1+..............................+2+1)
by adding both we will get
___________________________
S=(k+1)(k)
so the sum will be equal to
S=

so let us test the equation
for the first 3 even number there sums will be
2+4+6=12
by our equation 3^2+3=12
gave us the same answer so our equation is correct
The answer is 7 and 4/ 7+4+11 and 7-4=3!
It can be 8:12 or as a fraction it’s 8/12
