Answer 1

А) 6/11 x 2/5=12/55
б) 3 x 1 2/9= 3x 11/9=33/9=3 6/9=3 3/3
в) 2 3/4 x 1 1/11= 11/4x 12/11= 3
г) 1 2/3 + 14/15x 5/7= 5/3+ 2/3= 7/3
д) 4 7/27- 35/27x1/5= 115/27-7/27=108/27=4

Answer 2

A) 6/11 * 2/5

To solve this expression, we need to multiply the fractions. When multiplying fractions, we multiply the numerators together and the denominators together.

So, for 6/11 * 2/5, we have:

(6 * 2) / (11 * 5) = 12/55

Therefore, the result of 6/11 * 2/5 is 12/55.

B) 3 целых * 1 целая 2/9

To solve this expression, we need to multiply the whole numbers and then add the fraction part.

So, for 3 целых * 1 целая 2/9, we have:

3 * 1 + 2/9 = 3 + 2/9 = 3 2/9

Therefore, the result of 3 целых * 1 целая 2/9 is 3 2/9.

C) 2 целых 3/4 * 1 целая 1/11

To solve this expression, we need to multiply the whole numbers and then multiply the fraction parts.

So, for 2 целых 3/4 * 1 целая 1/11, we have:

(2 * 1) + (3/4 * 1/11) = 2 + 3/44 = 2 3/44

Therefore, the result of 2 целых 3/4 * 1 целая 1/11 is 2 3/44.

D) 1 целая 2/3 + 14/15 * 5/7

To solve this expression, we need to multiply the fractions and then add the whole number part.

So, for 1 целая 2/3 + 14/15 * 5/7, we have:

1 + (2/3 + 14/15 * 5/7) = 1 + (10/21 + 14/21) = 1 + 24/21 = 1 3/7

Therefore, the result of 1 целая 2/3 + 14/15 * 5/7 is 1 3/7.

E) 4 целых 7/27 - 35/27 * 1/5

To solve this expression, we need to multiply the fractions and then subtract the whole number part.

So, for 4 целых 7/27 - 35/27 * 1/5, we have:

(4 * 27 + 7) - (35/27 * 1/5) = (108 + 7) - (35/135) = 115 - 7/135

Therefore, the result of 4 целых 7/27 - 35/27 * 1/5 is 115 - 7/135.

I hope this helps! Let me know if you have any further questions.
