How many paper square with an area of 40 cm² will be needed to form a square with an area of 4 m²?

No. of paper square = 4 m^2/ 40 cm^2

= 40000cm^2 /40 cm^

= 1000 paper squares.

Thanks.

Step-by-step explanation:

D = ⅓

Step-by-step explanation:

Given the following data;

A = ⅙

B = ⅖

C = ⅒

To find what fraction of the chemical is D;

The sum of all the fractions of the chemical compound must be equal to one (1).

A + B + C + D = 1

Substituting the values, we would have;

⅙ + ⅖ + ⅒ + D = 1

Lowest common multiple (LCM) = 30

⅔ + D = 1

D = 1 - ⅔

Lowest common multiple (LCM) = 3

D = ⅓
