Answer:
it's 1/2
Change the mixed numbers into improper fractions:
3 [tex]\frac{1}{4}[/tex] = [tex]\frac{3*4+1}{4}[/tex] = [tex]\frac{12+1}{4}[/tex] = [tex]\frac{13}{4}[/tex]
2 [tex]\frac{3}{4}[/tex] = [tex]\frac{2*4+3}{4}[/tex] = [tex]\frac{8+3}{4}[/tex] = [tex]\frac{11}{4}[/tex]
Then you subtract them:
[tex]\frac{13}{4}[/tex] - [tex]\frac{11}{4}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]
And that's all you gotta do so your answer is B.
