Question

A) 5/34-7/51d) (11/20-0,75)+1/16

Answer 1

а) 1/101

d) -1/5+1/16=11/80

0/75=3/4

Answer 2

To simplify the given expressions, let's start by performing the calculations step by step:

A) 5/34 - 7/51

To subtract these fractions, we need to find a common denominator, which is the least common multiple (LCM) of 34 and 51, which is 102.

5/34 = (5/34) * (3/3) = 15/102 7/51 = (7/51) * (2/2) = 14/102

Now, we can subtract the fractions:

(15/102) - (14/102) = (15 - 14) / 102 = 1/102

B) (11/20 - 0.75) + 1/16

To add or subtract fractions, they need to have a common denominator. The common denominator for 20 and 16 is 80.

11/20 = (11/20) * (4/4) = 44/80 0.75 = 0.75 * (80/80) = 60/80

Now, we can perform the subtraction:

(44/80 - 60/80) = (-16/80) = -1/5

Finally, we can add the result to 1/16:

-1/5 + 1/16

To add these fractions, they need a common denominator, which is 80 (LCM of 5 and 16):

-1/5 = (-1/5) * (16/16) = -16/80 1/16 = (1/16) * (5/5) = 5/80

Now, we can add the fractions:

(-16/80) + (5/80) = (-16 + 5) / 80 = -11/80

So, the simplified expression is -11/80.
