a number whose fifth part increased by 2 is equal to its fourth part diminished by 2 is ?
"answer let the number be n . then , ( n / 5 ) + 2 = ( n / 4 ) - 2 â ‡ ’ ( n / 4 ) - ( n / 5 ) = 4 â ‡ ’ ( 5 n - 4 n ) / 20 = 4 â ˆ ´ n = 80 option : b"
divide(add(2, 2), subtract(divide(const_1, 2), divide(const_1, add(const_1, 2))))
