Answer
To find the missing value in the equation ( \frac{1}{3} = 2 ), we can cross-multiply. This gives us:
[1 \times 2 = 3 \times x]
From this, we get:
[x = \frac{2}{3}]
Thus, the missing value is ( \frac{2}{3} ).

Answer
Using the same cross-multiplication method for ( \frac{1}{7} = 7 ):
[1 \times 7 = 7 \times y]
So, this simplifies to:
[y = \frac{1}{7}]
The missing value is therefore ( \frac{1}{7} ).
