Answer:
1000
Step-by-step explanation:
To find the value of a digit in a number, set all the other digits to zero.
The value of 7 in 7042 is 7000.
The value of 7 in 427 is 007 = 7.
Then the question is "how many times larger is 7000 than 7?" That result is found by dividing 7000 by 7:
7000/7 = 1000
The 7 in 7042 is 1000 times larger than the 7 in 427.
_____
<em>Another way to consider this</em>
The 7 in 7042 is in the "thousands" place. The 7 in 427 is in the "ones" place. The thousands place is 3 places to the left of the ones place. Each place moved to the left increases the value by a factor of 10, so the value of a digit in the thousands place is 10×10×10 = 1000 times that of the same digit in the ones place.
