In the number 7,725 which places contain digits where one digit is ten times as great as the other one

Sagot :

the 7 in the thousands place represents 7,000

the 7 in the hundreds place represents 700

the ratio of 7,000 / 700 = 10

 . . . so the answer is the number in the thousands place is ten times as great as the number in the hundreds place
The given number is 7,725
now; we need to find which of the given digit is ten times greater as the other number next to the number.
=> 7, 725 = 7000 + 700 + 20 + 5
=> all numbers from ones is always ten times greater, why? Because when ones is multiplied by 10 the answer is tens, when tens is multiplied by 10 the answer s hundreds, and so on.
But we need to find the number that is exactly 10 times greater

=> 5 ones x 10 = 50 tens (the given number is 20 tens)
=> 20 tens x 10 = 200 hundreds (the given number in hundreds is 700)
=> 7 hundreds x 10 = 7 thousands (the given number is 7 thousands)

Thus, the answer is 700 and 7000
