Question

45 gram is what percentage of 4 kilogram​

Answer 1

Answer:

45 g is 1.125 percent of 4 kilogram

Step-by-step explanation:

Solution:

The 100 percent = 4 kilogram

By change the kilogram in grams:

The 100 percent = 4 × 1000 g = 4000 g

1 g =  ( 100 / 4000 ) percent

Multiplying by 45 on both sides  

45 g = ( ( 100 × 45 ) / 4000 ) percent

45 g = 1.125 percent

So

45 g is 1.125 percent of 4 kilogram.

Answer 2

Answer:

Step-by-step explanation:

Let x% of 4kg = 45 gram

=> (x/100) × 4000 grams = 45 gm

=> x × 40 gm = 45 gm

=> x = (45/40 )

=> x = 1.125%

Or

x = 1 1/8 %
