Answer:

\frac{5}{12}

Step-by-step explanation:

Because \frac{3}{5} is being multiplied by S, we can divide \frac{3}{5} from both sides of the equation. This will give us:

\frac{1}{4}÷\frac{3}{5}

But, that looks a bit hectic. Instead of dividing, you can multiply by the reciprocal (which is essentially how to divide fractions). So, instead of \frac{1}{4}÷\frac{3}{5}, you get:

\frac{1}{4}×\frac{5}{3}

When multiplying fractions, remember you can just multiply straight across-- numerator x numerator, then denominator x denominator.

By doing that, you get the fraction \frac{5}{12}

\frac{5}{12} cannot be simplified any more, so S=\frac{5}{12} is your answer :)

I hope this helps

A kite was broken into two triangles.
Mekhanik [1.2K]
<h2>Answer:</h2><h2>Area of the kite = 80 cm^{2} , Area of traingle = 40 cm^{2} and height of the triangle, h = 5 cm</h2>

Step-by-step explanation:

A kite is broken into two triangles

Given the base of the traingle, b = 16 cm

Height of the triangle, h = 5 cm

Area of traingle = \frac{1}{2} (b.h)

= \frac{1}{2} (16) (5)

= 40 cm^{2}

Area of the kite = area of triangle 1 + area of triangle 2

  = 40 + 40

 = 80 cm^{2}
