Question

1/4x+1/3x

2/5y-1/3y

9/4b-4/3b

Urgenttt plssss

Answer 1

Step-by-step explanation:

$\frac{1}{4} x + \frac{1}{3} x \\ \frac{3 x+ 4x}{12} = \frac{7x}{12}$

2》

$\frac{2}{5} y - \frac{1y}{3} \\ \frac{6y - 5y}{15} = \frac{y}{15}$

$\frac{9}{4} b - \frac{4}{3} b \\ = \frac{27b - 16b}{12} = \frac{11}{12} b$
