You find the product by using the rule for multiplying fractions. See the full explanation below.

Explanation:

The rule for multiplying fractions is to multiply the numerators and denominators separately:

color(red)(a)/color(blue)(c) xx color(red)(b)/color(blue)(d) = color(red)(a xx b)/color(blue)(c xx d)

Substituting the fractions we were given results in:

color(red)(1)/color(blue)(3) xx color(red)(3)/color(blue)(7) = color(red)(1 xx 3)/color(blue)(3 xx 7)

We an now cancel the common terms:

color(red)(1 xx cancel(3))/color(blue)(cancel(3) xx 7)

Resulting in:

color(red)(1)/color(blue)(7)
