Is 2/5 closer to 0, 1/2 or 1
Elza [17]

Answer:

1/2

Step-by-step explanation:

1/2 of 2/5 is 0.2 or as a fraction is 1/5

2/5 is closer to 1/5 because it is only 1/5 off, but for 0 2/5 is 2/5 off and for 1 2/5 is off by 3/5

Either way if this didn't explain right as it is merely a example.

2/5 overall is just closer to 1/2 than it is to 0.

Simplify the expression below. (2n/6n+4)(3n+2/3n-2)
andrezito [222]

Answer:

\frac{n}{3n-2}

Step-by-step explanation:

Given the expression:

\frac{2n}{(6n+4)} \cdot \frac{3n+2}{3n-2}

Using the distributive property: a \cdot (b+c) =a\cdot b+a\cdot c

\frac{2n}{2(3n+2)} \cdot \frac{3n+2}{3n-2}

Simplify:

\frac{2n}{2} \cdot \frac{1}{3n-2}

Simplify:

\frac{n}{3n-2}

Therefore, the simplified given expression is, \frac{n}{3n-2}
