Answer:

N = 3/8

Step-by-step explanation:

let the number be N

let's express the word sentence as a mathematical expression:

"a number multiplied by 2/5"

= "N" multiplied by 2/5

= N x (2/5)

= (2N/5) ------- (1)

"a number multiplied by 2/5 is 3/20" can be written as:

(2N/5) = 3/20 (multiplying both sides by 5)

2N = (3/20) x 5

2N = 3/4 (divide both sides by 2)

N = (3/4) ÷ 2

N = (3/4) x (1/2)

N = 3/8

-2.105 as a fraction?

Bezzdna [24]

The easiest way is if it doesn't need to be simplified. Multiply -2.105 by $\frac{1000}{1000}$ . You get the fraction $-\frac{2105}{1000}$ . While this is technically the answer, you can simplify this down to $\frac{421}{200}$ . Because 421 is a prime number, this can not be simplified any further. Therefore, the solution is $\frac{421}{200}$ .

$\frac{421}{200}$ .
