Answer 1

Answer:

(a) 30% of 86 = (30/100)×86

= 25.8

(b) (21/100)×200 = 42

(c) (80/100)×120 = 96m

(d) (20/100)×1500 = 300kg

Answer 2

Step-by-step explanation:

(a) 30% of 86

= $\frac{30}{100}$ × 86

= $\frac{3}{10}$ × 86

= 0.3 × 86

= 25.8

(b) 21% of 200

= $\frac{21}{100}$ × 200

= 21 × 2

= 42

(c) 80% of 120 m

= ($\frac{80}{100}$ × 120) m

= ( 8× 12) m

= 96 m

(g) 20% of 1500 Kg

= ($\frac{20}{100}$ × 1500) Kg

= ( 20 × 15) Kg

= 300 Kg
