If 8 widgets equal 4 curlicues and2 curlicues equal 3 goof-ups,then
16 widgets equal how many goof-ups?

Answers

so 8w=4c and 2c=3g. divide the first equation by 2 and you get 4w=2c. merge the two equation give you 4w=2c=3g, or 4w=3g. multiply 4 on both sides give you 16w=12g. So 16 widgets equal how 12 goof-ups?
