Answer 2

Б) 66/40=1 26/40
в) 103/61=1 42/61
г)456/300=1 156/300
д) 506/401=1 105/401

Answer 3

Let's solve each of these additions step by step:

а) 29/40 + 37/40

Since the denominators are the same (40), we can simply add the numerators:

(29 + 37) / 40 = 66 / 40

Now, we can simplify the fraction:

66 ÷ 2 / 40 ÷ 2 = 33 / 20

So, 29/40 + 37/40 = 33/20.

б) 58/61 + 45/61

Since the denominators are the same (61), we can simply add the numerators:

(58 + 45) / 61 = 103 / 61

Thus, 58/61 + 45/61 = 103/61.

в) 257/300 + 199/300

Since the denominators are the same (300), we can simply add the numerators:

(257 + 199) / 300 = 456 / 300

Now, we can simplify the fraction:

456 ÷ 12 / 300 ÷ 12 = 38 / 25

Therefore, 257/300 + 199/300 = 38/25.

г) 379/401 + 127/401

Since the denominators are the same (401), we can simply add the numerators:

(379 + 127) / 401 = 506 / 401

Thus, 379/401 + 127/401 = 506/401.

So, the results are: а) 33/20 б) 103/61 в) 38/25 г) 506/401
