I a, very confused on what the answer is to blank- 3/10=1/5
Yuri [45]

Answer:

a = 1/2

Step-by-step explanation:

a - 3/10 = 1/5

Add 3/10 to each side

a - 3/10 +3/10 = 1/5+3/10

a = 1/5+3/10

Get a common denominator

a= 1/5*2/2  +3/10

a = 2/10 +3/10

a = 5/10

Divide the top and bottom by 5

a = 1/2
