Question

fill in the boxes with equal and fraction

Answer 1

1st ◻ =

$\frac{9}{ - 13} = \frac{x}{26} \\ - 13x = 26 \times 9 \\ x = \frac{26 \times 9}{ - 13} \\ x = \frac{2 \times 9}{ - 1} \\ x = \frac{18}{ - 1} = - \frac{18}{1} = - 18$

Now,
2nd ◻ =

$\frac{ - 18}{26} = \frac{90}{y} \\ - 18y = 90 \times 26 \\ y = \frac{90 \times 26}{ - 18} \\ y = - 5 \times 26 \\ y = - 131$

Now,
3rd ◻ =

$\frac{90}{ - 131} = \frac{ - 117}{z} \\ 90z = - 117 \times( - 131) \\ z = \frac{ - 117 \times ( - 131)}{90} \\ z = \frac{- 13 \times ( - 131)}{10} \\ z = \frac{1703}{10} \\ z = 170.3$
