Read what the question asks for first.
Underline the unknown amount, then choose the operation.
Keep units the same.
Before calculating speed, area, volume, or scale, check cm, m, minutes, and yen.
For percentages, use base amount × percentage.
Example: 200 × 30% = 60.
For ratios, divide by the total ratio first.
If the ratio is 2:3, split the total into 5 equal parts.
For speed, connect speed, time, and distance.
Distance = speed × time. Time = distance ÷ speed.
