Question

The fractions that Adam chooses is 1 half, John chooses is 2 over 6, Ray chooses is 3 over 6. The ones that choose equivalent fractions are

  1. Adam and John
  2. John and Ray
  3. Adam and Ray
  4. Adam, John and Ray

Hint:

To find out whether the pair of fraction is equivalent we have to do cross multiplication. For this we have to multiply the numerator of first fraction and the denominator of second, and numerator of second fraction to the denominator of first. If the products are equal the fractions are equivalent and vice versa.

The correct answer is: Adam and Ray


The fractions that Adam chooses is 1 half
 John chooses is 2 over 6
Ray chooses is 3 over 6
for adam and john           for adam and ray         for john and ray

Therefore the ones who chose equivalent fraction are Adam and Ray.
