Represent the expression as a decimal number.

Question

( 2 x 100 ) + ( 7x1 ) + ( 2 x 1/10 ) + ( 9 x 1/100 ) + ( 4 x 1/ 1000 )

Answer 1

(4x1000)+(3x100)+(6x1/10)

Answer 2

Hello Brooke, There are two ways to do this problem. You were not clear.

( 2 x 100) + ( 7 x 1) + ( 2 x 1/10) + (9 x 1/100) + (4 x 1/1000)

= (200) + (7) + ( 2 ) + ( 9 ) + ( 4 ) ( Now add the 200 plus the 7 on top we have)

_____ ___ ___ ____ _______

1 1 10 100 1000

207 + 2 + 9 + 4

_____ ____ ___ ____

1 10 100 1000 ( Now the LCD by looking is 1000)

= ( 207,000) + (200) + ( 90 ) + ( 4) Now add the numerator giving)

____________________________________

1000

= 207,294

_________

1000

= 207.294 --------> Ansr

Second Way ( Set your calculator to at least 5 places--if you can)

( 2 x 100) + ( 7 x 1) + ( 2 x 1/10) + ( 9 x 1/100) + ( 4 x 1/1000)

2 x100 = 200.00 ---> (whole number with decimal point)

7 x1 = 7.00 -----> ( whole number with decimal point)

( 9 x 1/100) = 0.09000 ( with decimal point)

( 4 x 1/1000) = 0.00400 ( with decimal point)

Now add all the numbers with a decimal point) we have:

( 200.00 + 7.00 + 0.9000 + 0.00400 )

= 207.294 ( when added ) ----> Ansr

Hope this helps !!
