 Your equation is 1/5 + 1/3 =1/x To solve you have to find the common denominator which is 15 So (1/5)3 and (1/3)5

                                          = 3/15+5/15=8/15

                                                  8/15=1/x now cross multiply

                                                   =15/8

This is the answer I got.

Step-by-step explanation:

Answer:

  1/3, 0.5, 4/6, 4/5

Step-by-step explanation:

For the same numerator, the fraction with the larger denominator is the smaller fraction.

  0.5 = 1/2

So, we have two fractions with numerators of 1, and two fractions with numerators of 4. The smaller fraction with a numerator of 4 has a numerator that is more than half the denominator, so its value is more than 1/2.

The least-to-greatest order is ...

  1/3, 1/2, 4/6, 4/5

In the original number format, this is ...

  1/3, 0.5, 4/6, 4/5
