Answer:

  • 865

Step-by-step explanation:

Let the 3-digit number is <u>abc</u> = 100a + 10b + c.

<u>We have:</u>

  • 100a + 10b + c - 100c - 10b - a = 297
  • b = a - 6
  • a = 2c - 2

<u>Simplify the first equation:</u>

  • 99a - 99c = 297
  • a - c = 3
  • a = c + 3

<u>Solve for c by substitution:</u>

  • 2c - 2 = c + 3
  • 2c - c = 3 + 2
  • c = 5

<u>Find a:</u>

  • a = 3 + 5 = 8

<u>Find b:</u>

  • b = 8 - 2 = 6

<u>The number is:</u>

Tamara and Amir shared a candy bar. Tamara ate two fifths. Amir ate two fifths. How much is left?
marin [14]

Answer:

1/5

Step-by-step explanation:

Both Amir and Tamara ate 2/5 each.

2/5 + 2/5 = 4/5

If 4/5 of the candy bar was eaten, 1/5 of the candy bar remains because

5/5 - 4/5 = 1/5

(Remember that 5/5 just equals one whole, representing the whole candy bar)
