a number whose fifth part increased by 3 is equal to its fourth part diminished by 3 is ?
"answer let the number be n . then , ( n / 5 ) + 3 = ( n / 4 ) - 3 â ‡ ’ ( n / 4 ) - ( n / 5 ) = 6 â ‡ ’ ( 5 n - 4 n ) / 20 = 6 â ˆ ´ n = 120 option : a"
divide(add(3, 3), subtract(divide(const_1, 3), divide(const_1, add(const_1, 3))))
