Answer 2

To evaluate -1/2 + 2/3 + 4/5,

we can simply add the fractions:

-1/2 + 2/3 + 4/5 = (3/2) + (8/3) + (16/5)

= (35 + 82 + 163)/(23*5)

= (51)/(30)

= 17/10

So, -1/2 + 2/3 + 4/5 = 17/10.

• A fraction is a mathematical representation of a part of a whole. It is written as two numbers separated by a fraction bar, with the top number (numerator) representing the part and the bottom number (denominator) representing the whole.
• For example, 2/3 represents 2 parts out of 3 equal parts of a whole. Fractions are used in many areas of mathematics, including arithmetic, algebra, geometry, and calculus. They are also used in everyday life, for example, in representing amounts of money, ingredients in recipes, or distances.
• Fractions can be added, subtracted, multiplied, and divided, and can be simplified by dividing both the numerator and denominator by their greatest common factor.
