Keep It in Proportion.
Snider, Richard G.
Science Teacher, v52 n4 p24-28 Apr 1985
The ratio factors approach involves recognizing a given fraction, then multiplying so that units cancel. This approach, which is grounded in concrete operational thinking patterns, provides a standard for science ratio and proportion problems. Examples are included for unit conversions, mole problems, molarity, speed/density problems, and multiratios. (DH)
