Final answer:
To solve the equation m/4.5 = 2/5 for m, cross-multiple to get 5m = 9, and then divide both sides by 5 to find that m equals 1.8.
Step-by-step explanation:
The student is asking to solve for m in the equation m/4.5 = 2/5 where 2/5 is considered the scale factor. To solve for m, you would set up the equation and cross-multiply to find the value of m. Here is the step-by-step solution:
- Start with the given equation: m/4.5 = 2/5.
- Cross-multiply to get: 5m = 9.
- Divide both sides by 5 to solve for m: m = 9/5.
- m equals 1.8.
Therefore, m is 1.8 when using the scale factor of 2/5.
