Work out b(4½-3⅔)+1⅔​
Zolol [24]

Answer:

2 \frac{1}{2}

Step-by-step explanation:

Change the mixed numbers to improper fractions

(\frac{9}{2} - \frac{11}{3} ) + \frac{5}{3} ← the LCM of 2 and 3 is 6

= \frac{9(3)}{2(3)} - \frac{11(2)}{3(2)} + \frac{5(2)}{3(2)}

= \frac{27}{6} - \frac{22}{6} + \frac{10}{6}

= \frac{5}{6} + \frac{10}{6}

= \frac{15}{6}

= \frac{5}{2}

= 2 \frac{1}{2}
