answer: 1 1/6
Step-by-step explanation:
1/2+6/9
common denominator is 18 (2×9)
now lets divide what's bellow(denominators) by 18 , then multiply to numbers above the line(nominators) by that number and finally find sum of them
1) 18/2=9, 9×1=9
2)18/9=2, 2×6=12
answer will be sum of them with common denominator:
(12+9)/18=21/18
we can simplify both, up and down (denominator and nominator) of that rational number. I'll divide both by 3
(21:3)/(18:3)=7/6= 1 1/6
