This is fairly simple. Divide 2,871,000 by 10 and that's your answer!

Also, since you're dividing by a factor of 10 (or in this case, <em>10</em>) you can just take away as many places as are zeros in the number you're dividing from. This works for <em>10, 100, 1,000, 10,000, etc. </em>In this case, since there is only one zero in 10 you only take away one place marking, which gives you 287,100.
Answer:
Step-by-step explanation:
Hello, please consider the following.
a)

b)

Thank you.
The value B is 7. If we apply B=7 the answer is 17 for the expression 17×
Step-by-step explanation:
The given expression is 17×
Step:1
Form an equation from given data,
17×
= 17..............................(1)
(∵ product equal to 17)
Step:2
Check for alternatives by apply the value of B in eqn (1)
Assume be value of B for check the equation
B=1
Equation becomes,
17×
= 2.4286 ≠ 17
Take, B=2,
17×
= 4.8571 ≠ 17
Take, B=3,
17×
= 7.2857 ≠ 17
similarly,
B=7,
17×
= 17 (∵ The product equals to 17)
Result:
So, the answer for B is 7.
