Answer:
Ok, got it. The answer is 1/10.
Step-by-step explanation:
It helps a lot if you write out what they give you; in this case:
Ten million is what is known as a "place value". This is just a word that describes where an individual digit, or number, is placed within a bigger number. A few examples:
- In the number 1,754, the 1 is in the thousands place (a good way to remember this is to say it out loud, or in your head; you read this number as one thousand, seven hundred and fifty-four.) The 7 is in the hundreds place, the 5 is in the tens place, and the 4 is in the ones place. (For the 5 and the 4, a good way to remember is how many sets of 10, and how many sets of 1, you would need to reach the number 54. It would take 5 sets of 10, and 4 sets of 1. Let me know if this part doesn't make sense, and I'll do my best to explain it another way.)
- In the number 20,389, the 2 is in the ten-thousands place (it would take 2 sets of 10,000 to reach 20,000), the 0 is in the thousands place (you would not have any sets of 1,000), the 3 is in the hundreds place (because you would need 3 sets of 100), the 8 is in the tens place (you would need 8 sets of 10), and the 9 is in the ones place (you would need 9 sets of 1).
For your question, I'm going to write it out, same deal: 8 x 10 = 80, since they ask for the value of the 8, and it is in the 10 millions place. So our first number is 80 million, or 80,000,000. (You can count each zero as a "place", from right to left: ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions)
It's the same for the second part: 8 x 100 = 800, since they ask for the value of the 8, but this time in the 100 millions place. 800 million, or 800,000,000. The only difference, as the problem says, is that this 8 is in the hundred millions place.
The answer comes from asking: 80,000,000 divided by 800,000,000 is what? 80,000,000/800,000,000 = 0.1, which is the same thing as saying one-tenth.
