Power of ten questions6/26/2023 ![]() From the $100,000 question onward, missing a question decreases the contestant's winnings by the power of 10, meaning that he/she leaves with 10% of the money accumulated to that point (i.e. If the contestant missed either the $1,000 or $10,000 question, the contestant leaves empty-handed. If the contestant's guess is not within range, the game is over. ![]() If the contestant correctly answers the $1,000,000 question, they are then given the chance to win $10,000,000 by picking the exact percentage (rounded to the nearest 1%) out of that 10% range. For the $1,000,000 question, the correct answer is only revealed if the actual percentage is outside of the contestant's range. The size of the range decreases as cash awards increase:įor the first three questions, the correct answer to the question is revealed once the contestant locks in an answer by pulling down a handle or lever. In the money round, the contestant is given similar questions, and places a range on a scale from 0% to 100% that they believe includes the correct answer. The first player to earn three points advances to the money round to play for the top prize. The player who comes closest to the actual percentage without going over earns a point. If a contestant has not locked in their guess after ten seconds, the computer locks in the percentage the on which the contestant had currently rested. What percentage of Americans said they are afraid of circus clowns?) and the two contestants are given ten seconds to lock in their guess using a dial to select a percentage. 658, we go from 2 tens to 2 ones.) It appears, though, as if the decimal point has shifted one place left, or, with the whole number 26580, that a 0 has been taken off.Īs we move down the list - as we push the digits to the left through theĭecimal point - each number has been multiplied by 10.Īnd so we can easily multiply or divide by a power of 10 because of our systemĮach place belongs to the next power of 10.Īt this point, please "turn" the page and do some Problems.Two contestants attempt to predict the results of polls in a best-of-five elimination round. When we divide a whole number by a power of 10, theĪnswer will have as many decimal digits are there are 0's.Īgain, as in Lesson 2, consider this array:Īs we move up the list - as we push the digits one place right - the number has been divided by 10 because each place to the right is worth 10 times less. Starting from the right of 265, separate one decimal digit. Starting from the right of the whole number, separate as How do we divide a whole number by a power of ![]() ![]() There are no 0's to chop off We will see that we must place a decimal point to Now in Lesson 2 we saw that when a whole number ends in 0's, weīut when a whole number does not end in 0's - as 265 - then These example illustrate that, whenever we multiply or divideīy a power of 10, the digits do not change We simply move the decimal pointįinally, we must see how to divide a whole number by a Move the decimal point left as many places as How do we divide a decimal by a power of 10? Since money has two decimal digits, we added on a 0. Since 50 pounds are ten times 5 pounds, they will cost ten Pounds of sugar cost $2.79, how much will 50 pounds cost?Īnswer. The answer is a whole number, 732, which we write without a decimal However, since all the digits fall to the left of the decimal point, Move the decimal point right as many placesĪs there are 0's in the power. How do we multiply a decimal by a power of 10? The student should let go of that written method immediately. But it is not skillful, and it does not take advantage of positional numeration. Traditional multiplication would eventually give the right answer (we hope). How do we multiply a whole number by a power of 10?Īdd on as many 0's as appear in the power.ĭoing that is an example of skill in arithmetic, which is to be able to do a problem as quickly and as easily as possible. How do we multiply a decimal by a power of 10?.How do we multiply a whole number by a power.In this Lesson, we will answer the following:
