1. () meter is 1.2 times more than 5m, 40kg is 20% less than () kg

1. () meter is 1.2 times more than 5m, 40kg is 20% less than () kg

5×（1+1/5）=6
40÷（1-20%）=50
So 1, (6) m is 1.2 times more than 5 m, 40 kg is 20% less than (50) kg

() m is 20% more than 20 m and 60kg is 40% less than () kg
We need formulas, not equations!

(24) meters is 20% more than 20 meters, and 60kg is 40% less than (100) kg
20 × (1 + 20%) = 24m
60 ÷ (1-40%) = 100 kg

40 meters is 10% more than 10 meters, and () dry gram is 40% less than 15 dry gram

40 m is more than 10 m (300%), (9) dry gram is 40% less than 15 dry gram
