Answer:

b = 1/4

Step-by-step explanation:

  • Take the given fractions : 3/2 and 7/4 and find a common denominator.

We will use 4 as a common denominator.

  • In order for the denominator of 3/2 to get to 4, you need to multiply by 2.

3 × 2 = 6        2 × 2 = 4

  • New fraction: 6/4

Now we have the equation 6/4 + b = 7/4

  • 7/4 - 6/4 = 1/4
