Question

If a number is divided by 11 over 3 to negative 3 over 19. The number is _________.

  1. negative 33 over 87
  2. negative 33 over 119
  3. negative 33 over 188
  4. negative 33 over 247

Hint:

Use simple alzebra rule to solve the questions.

The correct answer is: negative 33 over 247


    STEP BY STEP SOLUTION
    Let the number be x
    If a number divided by 11 over 13 to give fraction numerator negative 3 over denominator 19 end fraction
    x space divided by 11 over 13 space equals space fraction numerator negative 3 over denominator 19 end fraction
    x space equals space fraction numerator negative 3 over denominator 19 end fraction space cross times 11 over 13
x space equals space minus 33 over 247
    HENCE, THE NUMBER IS negative 33 over 247

    Determine the distance between 2.5 and - 0.5 on the number line shown

    STEP BY STEP SOLUTION
    We know that the distance is the difference between the numbers.
    So, we will subract -0.5 from 2.5
