Question 65851
Evaluate the expression.
- 5/6 * ( - 9/10 ) divided by 17/20
First flip the 17/20 and multiply by the reciprocal.
{{{(-5/6)*(-9/10)*(20/17)}}}
Now notice that there are an even number of - signs, so your answer whil be positive.  Also do some cancelling before you multiply, because life is too short to simplify after the fact.
{{{(-5/(3*2))*((-3*3)/(10))*((2*10)/17)}}}
{{{(-5/(cross(3)*cross(2)))*((-3*cross(3))/cross((10)))*((cross(2)*cross(10))/17)}}}
{{{(-5/1)*(-3/1)*(1/17)}}}  Multiply the numerators and denominators that are reamining.
{{{highlight(15/17)}}}
Happy Calculating!!!
