What number is represented by point P?
likoan [24]

Answer:

0.0057

Step-by-step explanation:

  • Narrow it down.
  • The point P is between 5 * 10^-3 and and 6*10^-3
  • When you go to the bottom line, P is on the 7th division from the left.
  • Going from left to right increases P
  • P is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.
  • One of the answers is 5.7 * 10^-3
  • The other answer is .0057
  • I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.
  • If it is not correct, then 5.7 * 10^-3 is the answer.
