Question

find y if 13 by 11 ×22 by 39 ×y=1 by 9​

Answer 1

Answer:

Given

$\frac{13}{11} \times \frac{22}{39} \times y = \frac{1}{9} \\ 13 \times \frac{2}{39} \times y = \frac{1}{6} \\ \frac{2}{3} y = \frac{1}{9} \\ y = \frac{1}{9} \times \frac{3}{2 } \\ y = \frac{1}{3 \times 2} \\ y = \frac{1}{6}$
