The area lf the triangle is 2/5.the height is 6/5, what is the base, in fraction form?

The base is 2/3.

Step-by-step explanation:

Recall that the area of a triangle of base b and height h is given by:

A = (1/2)(base)(height).  If we solve this for (base), we get  2A/(height).

Here, (base) =

2(2/5)       4/5

= = 4/6 = 2/3 (answer)

    6/5        6/5

b =

Step-by-step explanation:

The formula for the area of a triangle is . We fill in what we know.

0.4 = --- convert fractions to decimal

0.4 = 0.6b --- simplify fractions

b = 0.6666666... --- divide both sides by 0.6

b = --- convert to fraction

answer: .64
