Answer 2

Calculation of Expressions

a) To calculate 1 - 4/15, we subtract the fraction 4/15 from 1.

b) To calculate 1 - 9/32, we subtract the fraction 9/32 from 1.

c) To calculate 1 - 28/77 - 49/77, we subtract the fractions 28/77 and 49/77 from 1.

Let's calculate these expressions step by step.

a) 1 - 4/15: To subtract fractions, we need to find a common denominator. In this case, the common denominator is 15. We can rewrite 1 as 15/15 to have the same denominator.

1 - 4/15 = 15/15 - 4/15 = (15 - 4)/15 = 11/15.

b) 1 - 9/32: Again, we need to find a common denominator. The common denominator here is 32. We can rewrite 1 as 32/32.

1 - 9/32 = 32/32 - 9/32 = (32 - 9)/32 = 23/32.

c) 1 - 28/77 - 49/77: Here, the fractions already have a common denominator, which is 77.

1 - 28/77 - 49/77 = (77/77) - (28/77) - (49/77) = (77 - 28 - 49)/77 = 0/77 = 0.

So, the answers to the given expressions are: a) 1 - 4/15 = 11/15. b) 1 - 9/32 = 23/32. c) 1 - 28/77 - 49/77 = 0.
