Answer:
7
Step-by-step explanation:
We want to find the number 4-digit of positive integers n such that removing the thousands digit divides the number by 9.
__
Let the thousands digit be 'd'. Then we want to find the integer solutions to ...
n -1000d = n/9
n -n/9 = 1000d . . . . . . add 1000d -n/9
8n = 9000d . . . . . . . . multiply by 9
n = 1125d . . . . . . . . . divide by 8
The values of d that will give a suitable 4-digit value of n are 1 through 7.
When d=8, n is 9000. Removing the 9 gives 0, not 1000.
When d=9, n is 10125, not a 4-digit number.
There are 7 4-digit numbers such that removing the thousands digit gives 1/9 of the number.
what is the question sir. after what
Solve for m:
1/4 = m/24
1/4 = m/24 is equivalent to m/24 = 1/4:
m/24 = 1/4
Multiply both sides of m/24 = 1/4 by 24:
(24 m)/24 = 24/4
(24 m)/24 = 24/24×m = m:
m = 24/4
24/4 = (4×6)/4 = 6:
Answer: m = 6
