4 2/5 - (3 - 3/10) 3 1/81Convert the mixed number 4 2/5 to an improper fraction:4 2/5 = 22/5Now simplify the expression using the order of operations (PEMDAS):
(22/5) - (3 - 3/10) 3 1/81= 22/5 - (3 - 3/10) 3 1/81= 22/5 - (30/10 - 3/10) 3 1/81= 22/5 - (27/10) 3 1/81= 22/5 - (81/10) * 1/81= 22/5 - 8/5= (22 - 8)/5= 14/5
Therefore, 4 2/5 - (3 - 3/10) 3 1/81 = 14/5 = 2 4/5
4 2/5 - (3 - 3/10) 3 1/81
Convert the mixed number 4 2/5 to an improper fraction:
4 2/5 = 22/5
Now simplify the expression using the order of operations (PEMDAS):
(22/5) - (3 - 3/10) 3 1/81
= 22/5 - (3 - 3/10) 3 1/81
= 22/5 - (30/10 - 3/10) 3 1/81
= 22/5 - (27/10) 3 1/81
= 22/5 - (81/10) * 1/81
= 22/5 - 8/5
= (22 - 8)/5
= 14/5
Therefore, 4 2/5 - (3 - 3/10) 3 1/81 = 14/5 = 2 4/5
