3/5 + blank = 1 1/2

trying to figure out the blank

3/5 + blank = 1 1/2

3/5 + blank = 3/2
3/5 - 3.5 + blank = 3/2 - 3/5 , whatever I do to one side, I must do to the other
0 + blank = 15/10 - 6/10 , I assume you know how to add or subtract fractions
blank = 9/10

Now do your other post in the same way

3/5 + x = 1 1/2

3/5+x = 3/2
X = 3/2-3/5 = 15/10-6/10 = 9/10.

To find the value of the blank, we need to solve the equation:

3/5 + blank = 1 1/2

To solve this equation, we can follow these steps:

Step 1: Convert the mixed number 1 1/2 into an improper fraction.

1 1/2 = (2*1 + 1)/2 = 3/2

Step 2: Rewrite the equation with the improper fraction.

3/5 + blank = 3/2

Step 3: Find a common denominator for the fractions on both sides of the equation. In this case, the common denominator is 10 (the least common multiple of 5 and 2).

Step 4: Convert the fractions on both sides to have the same denominator of 10.

(3/5) * (2/2) + (blank) * (10/10) = (3/2) * (5/5)

6/10 + (blank) * (10/10) = 15/10

Step 5: Simplify the equation.

6/10 + (blank) = 15/10

Step 6: Subtract 6/10 from both sides to isolate the variable.

(blank) = 15/10 - 6/10

(blank) = 9/10

So, the value of the blank is 9/10.
