To have batting averages over 0.500 how many hits in 45 times at bat would Raul and Karen need?

Question

I don’t know jow to do it also I need to show my work.

Answer 1

Equivalent ratios. Let x = the number of hits they need:

x/45 ≥ 0.500/1

Solve for x. Round up to the next whole number (cause you can't have part of a hit).
