Question

4 16/25 -(-5 4/15) +(-75/9) -8 4/75

Answer 1

416/25-(-54/15)+(-75/9)-84/75=416/25+54/15-75/9-84/75=809/75

Answer 2

To solve the expression, let's first convert all mixed numbers into improper fractions:

4 16/25 = (4 * 25 + 16)/25 = 116/25 -(-5 4/15) = 5 4/15 = (5 * 15 + 4)/15 = 79/15 -8 4/75 = (8 * 75 + 4)/75 = 604/75

Now, the expression becomes:

116/25 + 79/15 - 75/9 - 604/75

To add and subtract these fractions, we need a common denominator. The common denominator for 25, 15, 9, and 75 is 225. Let's convert all fractions to have a denominator of 225:

116/25 = (116 * 9)/225 = 1044/225 79/15 = (79 * 15)/225 = 1185/225 75/9 = (75 * 25)/225 = 1875/225 604/75 = (604 * 3)/225 = 1812/225

Now the expression becomes:

1044/225 + 1185/225 - 1875/225 - 1812/225

Now, we can combine the fractions:

(1044 + 1185 - 1875 - 1812)/225 = (417/225) * (225/225) [Finding a common denominator] = 417/225

So, the final result is 417/225.
