Question

Simplyify using properties 1/7 x 2/9 - 3/4 x 1/9 + 2/9 x 1/1

Answer 1

Step-by-step explanation:

$\frac{1}{7} \times \frac{2}{9} - \frac{3}{4} \times \frac{1}{9 } + \frac{2}{9} \times \frac{1}{1} \\ = \frac{7}{63} - \frac{3}{36} + \frac{2}{9} \\ = \frac{28 - 21 + 56}{252} \\ = \frac{63}{252} \\ = \frac{1}{4}$
