Question

the mean of 2÷5,5÷7,3÷5, and 2÷7 is .......​

Answer 1

Answer:

mean method =a+b/2

Step-by-step explanation:

2/5+5/7+3/5+2/7*2. =2.5+1.4+1.6+3.5/2

=9.0/2

=4.5

Answer 2

Answer:

The mean of  $\frac{2}{5}$ , $\frac{5}{7}$ , $\frac{3}{5}$ , $\frac{2}{7}$ is $\frac{1}{2}$

Step-by-step explanation:

We need to find the mean of : $\frac{2}{5}$ , $\frac{5}{7}$ , $\frac{3}{5}$ , $\frac{2}{7}$

We know that mean is the average of the numbers.

Therefore, Mean = $\frac{Sum Of All Nos.}{No. OfValues}$

Sum of values =  $\frac{2}{5}$ + $\frac{5}{7}$ + $\frac{3}{5}$  + $\frac{2}{7}$

                        = 1 + 1

                        = 2

No. of values = 4

Therefore, Mean = 2/4

                            = 1/2

                            = 0.5

Therefore, the mean of  $\frac{2}{5}$ , $\frac{5}{7}$ , $\frac{3}{5}$ , $\frac{2}{7}$ is $\frac{1}{2}$
