In 2012, the movie “The Avengers” made $15 x 108 worldwide. How much money is this?
In this lesson you will learn how to mentally evaluate expressions with powers of ten by using patterns in place value.
When you multiply a number by a power of ten, the value of each digit increases ten times for each power. 5 4 x 10 = 4 x 100,000 = 400,000 4 2 4 x 10 = 4 x 10,000 = 40,000 4 x 10 = 4 x 100 = 400 3 4 x 10 = 4 x 1,000 = 4,000 = 4 x 10 = 40 1 4 x 10
When you divide a number by a power of ten, the value of each digit decreases ten times for each power. = 30. = 300.÷100 = 300.÷ 10 = 3. 5 4 3 2 1 300 ÷10 300 ÷10 300 ÷10 300 ÷10 300 ÷10 = .03 = 300.÷100,000 = 300.÷10,000 = 300.÷ 1,000 = .003 = .3
Thinking that a number ends at the ones place. 3 3. = 3.00000
You can mentally evaluate an expression with a power of ten by shifting the decimal point for each power. 539 x 104 5,390,000. 539,000. 53,900. 5,390,000 5,390. 539.
You can mentally evaluate an expression with a power of ten by shifting the decimal point for each power. 0.416 x 105 41,600 0.416 41,600. 41,600. 4,160. 4,160. 41.6 4.16 416.
You can mentally evaluate an expression with a power of ten by shifting the decimal point for each power. 60.4 ÷ 102 0.604 0.604 60.4 6.04
You can mentally evaluate an expression with a power of ten by shifting the decimal point for each power. 4 ÷ 103 0.004 0.004 0.04 0.04 0.004 0.4 4.
How much money is $15 x 108? 150. 15,000. 15. 1500. 1,500,000. 15,000,000. 150,000. 1,500,000,000. 150,000,000. In 2012, the movie “The Avengers” made $1,500,000,000.
In this lesson you have learned how to mentally evaluate expressions with powers of ten by using patterns in place value.
