Will Make Brainiest if you awnser. Convert these unlike fractions to equivalent like fractions and add them. You must use the LCD to get the answer correct. If possible, reduce the final sum.
1. 1/5=

2. 2/3=

3. 1/5 + 2/3=

Find the lowest common denominator of the 2 denominators

Step-by-step explanation:

The common in both denominator is 15.

3: 3,6,9,12,15,18,21,24,27,30

5: 5,10,15,20,25.30,35,40,43,50

Since 5x3 is 15, 1/5 x 3/3= 3/15

Since 3x5 is 15, 2/3 x 5/5= 10/15

3/15 is equivalent to 1/5 and 10/15 is equivalent to 2/3.

3/15 + 10/15 is equal to 13/15

13/15 can't be simplified because they are both odd numbers and they have less than 2 factors.

Hope this helped! Have a nice day! :D  Step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
