Hi Mark,

One trillion usually means 10¹² or one million million (in some places it is 10¹⁸ but that is very rare). Since one million is 10^6 and we can change the numbers to

7.9 trillion = 7.9 × 10¹²

301 million = 301 ×10⁶

So our division is

7.9 × 10¹² ÷ 301 ×10⁶

We have cancel one million or 10⁶ from both to get

7.9 × 10⁶÷ 301

So our dividin 7.9 trillion by 301 million is the same as dividing 7.9 million by 301 or

7900000÷301

You can use long division to complete the division

Hope this helps,

Janice
