to the nearest millimeter a cell phone is 78 mm long and 34 mm wide what is the ratio of the width and length

Answer 1

First of all, your English grammar needs as much help as your math.

A sentence begins with a capital letter and ends with a period.

A question begins with a capital letter and ends with a question mark.

If you do not think this is important, I suggest you submit your SAT essay written the lack of grammar shown in your question.

The ratio you want is (apparently) the width to the length, i.e. 34/78=.=.436
