Question

Calculate: (6,666,666×666,666)/(1+2+3+4+5+6+5+4+3+2+1)− (777,777×777,777)/(1+2+3+4+5+6+7+6+5+4+3+2+1)

Answer 1

Answer:

1066528471

Step-by-step explanation:

$\frac{6,666,666*666,666}{1+2+3+4+5+6+5+4+3+2+1}$  -  $\frac{777,777*777,777}{1+2+3+4+5+6+5+4+3+2+1}$

The lowest common multiple is 1+2+3+4+5+6+5+4+3+2+1, so that;

= $\frac{(6,666,666*666,666)-(777,777*777,777)}{1+2+3+4+5+6+5+4+3+2+1}$

= $\frac{(444443955600)-(60493706170}{1+2+3+4+5+6+5+4+3+2+1}$

= $\frac{38395024940}{36}$

= 1066528471

The solution to the given question is 1066528471.
