#### BACK to Ladder Unit Conversion and Dimensional Analysis

To complete: $$\frac{54}{32 \cdot 45}$$ You can type either of these two things into your calculator: $$54 / 32 / 45 \: \: \: \text{or} \: \: \: 54 / (32 \cdot 45)$$ But, do NOT type! $$\require{enclose} \enclose{horizontalstrike}{54 / 32 \cdot 45}$$ which will give the wrong answer!

Evaluate each of the expressions below using a calculator.

1. $$\frac{86}{12 \cdot 77}$$
2. $$\frac{61}{37 \cdot 7}$$
3. $$\frac{11}{95 \cdot 54}$$
4. $$\frac{96}{6 \cdot 7}$$
5. $$\frac{46 \cdot 70}{64 \cdot 47 \cdot 35}$$
6. $$\frac{61 \cdot 89}{98 \cdot 56 \cdot 46 \cdot 35}$$
