Twelve millionths in digit form?

.00000003 i think but i might be wrong

12 million is written as 12,000,000. There are six zeros in a million, so you can either add six zeros to 12 or move the decimal point over six places to the right. Either method will give you the same answer of 12,000,000

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
