Answer 2

Sure, I'd be happy to help you with these calculations:

а) -6 + 4 5/8 First, let's convert the mixed number 4 5/8 to an improper fraction: 4 5/8 = 8 * 4 + 5 = 32 + 5 = 37/8

Now add -6 to 37/8: -6 + 37/8 = -48/8 + 37/8 = -11/8

So, -6 + 4 5/8 equals -11/8.

б) 2 21/26 + (-3 4/13) First, let's convert both mixed numbers to improper fractions: 2 21/26 = 26 * 2 + 21 = 52 + 21 = 73/26 -3 4/13 = 13 * -3 + 4 = -39 + 4 = -35/13

Now add 73/26 to -35/13: To add fractions with different denominators, we need a common denominator. The least common multiple (LCM) of 26 and 13 is 26 * 13 = 338.

Adjust the fractions to have a common denominator of 338: 73/26 * 13/13 = 949/338 -35/13 * 26/26 = -910/338

Now add the adjusted fractions: 949/338 + (-910/338) = 39/338

So, 2 21/26 + (-3 4/13) equals 39/338.
