Divide 20 chocolates between Adi and Suresh such that adi gets 60% while Suresh gets 40% of the chocolates
Eddi Din [679]

Hello!

To find how much chocolate Adi and Suresh receives, you need to convert the percentage to a decimal, then you multiply that decimal by the total number of chocolates, which is 20.

To convert percentages to decimals, divide the percentage by 100, and remove the percentage.

60% / 100 = 0.60

20% / 100 = 0.20

Then, we multiply 0.60 and 0.20 by 20.

0.60 x 20 = 12

0.40 x 20 = 8

Therefore, Adi gets 12 chocolates and Suresh gets 8 chocolates.

Fran has 7 sheets of paper for a colouring project. If she only uses 1/3 of a sheet of paper per drawing how many drawings can s
Sav [38]
So we can make an equation for this, being 7=1/3x, as that effectively says she can make 3 drawings per page.

Knowing this, we can multiply it by 3 to get x=21 (since if she can draw 3 drawings per page, we can imagine that if each drawing took a page she would need 3 times the pieces of paper), therefore she can make 21 drawings.
