Question

Puneti paranteze astfel incat egalitatea sa fie adevarata: 9:8+7:6+5:4+3:3=1

Answer 1

$\bf 9:\Big\{8+7:\big\{6+\big[5:\big(4+3:3\big)\big]\big\}\Big\}=$

$\bf 9:\Big\{8+7:\big\{6+\big[5:\big(4+1\big)\big]\big\}\Big\}=$

$\bf 9:\Big\{8+7:\big[6+\big(5:5\big)\big]\Big\}=$

$\bf 9:\Big[8+7:\big(6+1\big)\Big]=$

$\bf 9:\Big(8+7:7\Big)=$

$\bf 9:\Big(8+1\Big)=$

$\bf 9:9 = \pink{\underline{1}}$
