Question

tell me these all please ​

Answer 1

Step-by-step explanation:

a) 20% is also written as 20/100

= 20/100× 420 = 84

b) 4/5% of 5600 km

4/5/100×5600km (5/100 will go up and become in multiplication)

= 4×5/100×5600km

1120km

c)50 1/2% of 150 kg

so we will first convert mixed fraction into improper fraction= 101/2%

101/2/100 ×150 kg ( 2/100 will go up and become in multiplication)

101×2/100× 150kg

=3030kg
