Question

What does 3/2+b=7/4 eqaul

Answer 1

Answer:

$b=\frac{1}{4}or0.25$

Step-by-step explanation:

The trick here is to multiply 3/2 by 2/2 to make the base 4, and then subtract.

$\frac{3}{2} +b=\frac{7}{4} \\\frac{2}{2} *\frac{3}{2} +b=\frac{7}{4} \\\frac{6}{4} +b=\frac{7}{4}\\ b=\frac{7}{4} -\frac{6}{4}\\ b=\frac{7-6}{4}\\ b=\frac{1}{4}$

And that is our answer!
