To simplify the expression 4-4/15-11/15+2/23, we need to find a common denominator for the fractions. The least common denominator of 15 and 23 is 345. Then, we rewrite the fractions with the common denominator: 4 - (4/15)*23/23 - (11/15)*23/23 + (2/23)*15/15 Simplifying the fractions: 4 - (92/345) - (253/345) + (30/345) Combining like terms: = 4 - 92/345 - 253/345 + 30/345 = 4 - 315/345 + 30/345 Now, we add and subtract the fractions: = 4 - (315 - 30)/345 = 4 - 285/345 Simplifying the fraction: = 4 - 19/23 Finally, subtracting the fractions: = (4*23 - 19)/23 = 92 - 19/23 So, 4-4/15-11/15+2/23 simplifies to 92 - 19/23.
