First we will simplify the mixed fraction
6 1/5 ={(6*5)+1}/5 = 31/5
4 3/10 = { (4*10) + 3}/10 = 43/10
Similarly, 1 1/2 = 3/2
So the equation becomes:
31/5 - (43/10 - 3/2)
Opening the bracket
31/5 - 43/10 +3/2
Taking LCM
{(31*2) -43 + (3*5) }/10 = (62-43+15)/10 = 34/10
= 3.4 or 17/5
6 1/5 ={(6*5)+1}/5 = 31/5
4 3/10 = { (4*10) + 3}/10 = 43/10
Similarly, 1 1/2 = 3/2
So the equation becomes:
31/5 - (43/10 - 3/2)
Opening the bracket
31/5 - 43/10 +3/2
Taking LCM
{(31*2) -43 + (3*5) }/10 = (62-43+15)/10 = 34/10
= 3.4 or 17/5
