What is the best estimate of the sum of the fraction? 31/4 +17/3 +8/18
Bogdan [553]

The best estimate of the sum of the expression given is \rm 13 \dfrac {31}{26}

What is a Fraction ?

A fraction is written as p/q , where q \rm \ne 0

It is asked to determine the sum of the fraction

31/4 + 17/3 + 8/18

Taking the LCM of 4 , 3 , 18

LCM of 4 , 3 ,18 is 36

Therefore

\rm \dfrac{ 31 *9 + 17 *12 + 8 *2}{36 }

(279+204+16) /36

499 / 36

\rm 13 \dfrac {31}{26}

Therefore the best estimate of the sum of the expression given is \rm 13 \dfrac {31}{26}.
