60% expressed as a ration is StartFraction 60 Over 100 EndFraction. What is this as a fraction in its reduced form?

Leno4ka [110]

Answer:

3/5

Step-by-step explanation:

60% means 60 out of 100. For example if you get 60 marks in an exam of 100 marks. This means you got 60% marks.

Which is 60/100. This fraction can further be reduced to 6/10 [divide both numerator and denominator by 10)

6/10 = 3/5 [divide both numerator and denominator by 2)

So, the reduced form of 60% =3/5

Answer:

$(\frac{dy}{dt})^2=sin^2t$

Step-by-step explanation:

$y=cost$

DE : $(\frac{dy}{dt})^2=1-y^2$

If y is a solution of given DE then it satisfied the DE.

Differentiate w.r.t t

$\frac{dy}{dt}=-sint$

Using the formula

$\frac{d(cosx)}{dx}=-sinx$

LHS: $(\frac{dy}{dt})^2=(-sint)^2=sin^2t$

RHS

$1-y^2=1-cos^2t=sin^2t$

By using the formula

$sin^2t=1-cos^2t$

LHS=RHs

Hence, y is a solution of given DE

$(\frac{dy}{dt})^2=sin^2t$
