Question

A)1 -5/9 б)1 +3 3/7 в)9-5/6 г) 5 -1 4/5

Answer 1

А) 4/9
б) 4 3/7
в) 8 1/6
г)3 1/5

Answer 2

To perform the given operations, let's simplify each expression:

A) 1 - 5/9 To subtract a fraction, the denominators must be the same. Since 9 is the least common multiple of 9 and 1, we can rewrite 1 as 9/9 and proceed: 1 - 5/9 = 9/9 - 5/9 = (9 - 5)/9 = 4/9

б) 1 + 3 3/7 To add a mixed number, we first add the whole numbers and then the fractional parts. We get: 1 + 3 3/7 = 1 + 3 + 3/7 = 4 + 3/7 = 4 3/7

в) 9 - 5/6 No further simplification needed as it's already in its simplest form.

г) 5 - 1 4/5 Again, for subtraction of mixed numbers, we perform the subtraction separately for the whole numbers and the fractions: 5 - 1 4/5 = 5 - (1 + 4/5) = 5 - 9/5 = (25/5) - (9/5) = (25 - 9)/5 = 16/5

So, the simplified expressions are: A) 4/9 б) 4 3/7 в) 9 - 5/6 (unchanged) г) 16/5
