Question

fill in the boxes 5/4= [. ] /16 = 25\ [. ]​

Answer 1

1st case:

$\frac{5}{4} = \frac{?}{16} \\ = > \frac{5}{4} = \frac{x}{16} \\ = > x = \frac{5 \times 16}{4} \\ = > x = 5 \times 4 \\ = > x = 20$

2nd case:

$\frac{5}{4} = \frac{25}{?} \\ = > \frac{5}{4} = \frac{25}{y} \\ = > 5y = 4 \times 25 \\ = > y = \frac{4 \times 25}{5} \\ = > y = 4 \times 5 \\ = > y = 20$
