( 55 и 77 сократили на 11; а 12 и 48 на 12); ________ 4)) 21/40: 3/4= 21/40• 4/3= 21/10• 1/3= 7/10• 1/3= 7/(10•3)= 7/30. (Сократили 40 и 4 на 4; а 21 и 3 на 3); ___________ 5)) 27/50: 9/25= 27/50• 25/9= 27/2• 1/9= 3/2• 1/1= 3/2= 1 1/2. (Сократили 50 и 25 на 25; а 27 и 9 на 9); ____________ 6) 63/64: 45/56= 63/64• 56/45= 7/64• 56/5= 7/8• 7/5= (7•7)/(8•5)= 49/40= 1 9/40. ( сократили 63 и 45 на 9; а 64 и 56 на 8); ___________ 7)) 5/8: 5/32= 5/8• 32/5= 1/8• 32/1= 1/1• 4/1= (1•4)/(1•1)= 4/1= 4. (Сократили 5 и 5 на 5; а 32 и 8 на 8); _________ 8)) 14/55: 1/5= 14/55• 5/1= 14/11• 1/1= 14/11= 1 3/11. (Сократили 55 и 5 на 5).

Answer 2

1) To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction. Let's solve the first division problem step by step:

Step 1: Convert the whole numbers to fractions. 11 can be written as 11/1 and 3 as 3/1. Step 2: Multiply the first fraction by the reciprocal of the second fraction. Step 3: Simplify the resulting fraction if possible.

Applying these steps to the first division problem, we have:

11/15 ÷ 3/8 = (11/1) * (8/3) = (11 * 8) / (15 * 3) = 88/45.

Therefore, 11/15 ÷ 3/8 = 88/45.

2) Let's solve the second division problem step by step:

6/35 ÷ 18/25 = (6/35) * (25/18) = (6 * 25) / (35 * 18) = 150/630.

To simplify the resulting fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 30.

150/630 ÷ 30/30 = (150/30) / (630/30) = 5/21.

Therefore, 6/35 ÷ 18/25 = 5/21.

3) Let's solve the third division problem step by step:

12/55 ÷ 48/77 = (12/55) * (77/48) = (12 * 77) / (55 * 48) = 924/2640.

To simplify the resulting fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 132.

924/2640 ÷ 132/132 = (924/132) / (2640/132) = 7/20.

Therefore, 12/55 ÷ 48/77 = 7/20.

4) Let's solve the fourth division problem step by step:

21/40 ÷ 3/4 = (21/40) * (4/3) = (21 * 4) / (40 * 3) = 84/120.

To simplify the resulting fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 12.

84/120 ÷ 12/12 = (84/12) / (120/12) = 7/10.

Therefore, 21/40 ÷ 3/4 = 7/10.

5) Let's solve the fifth division problem step by step:

27/50 ÷ 9/25 = (27/50) * (25/9) = (27 * 25) / (50 * 9) = 675/450.

To simplify the resulting fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 225.

675/450 ÷ 225/225 = (675/225) / (450/225) = 3/2.

Therefore, 27/50 ÷ 9/25 = 3/2.

6) Let's solve the sixth division problem step by step:

63/64 ÷ 45/56 = (63/64) * (56/45) = (63 * 56) / (64 * 45) = 3528/2880.

To simplify the resulting fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 48.

3528/2880 ÷ 48/48 = (3528/48) / (2880/48) = 73/60.

Therefore, 63/64 ÷ 45/56 = 73/60.

7) Let's solve the seventh division problem step by step:

5/8 ÷ 5/32 = (5/8) * (32/5) = (5 * 32) / (8 * 5) = 160/40.

To simplify the resulting fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 40.

160/40 ÷ 40/40 = (160/40) / (40/40) = 4/1.

Therefore, 5/8 ÷ 5/32 = 4/1.

8) Let's solve the eighth division problem step by step:

14/55 ÷ 1/5 = (14/55) * (5/1) = (14 * 5) / (55 * 1) = 70/55.

To simplify the resulting fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 5.

70/55 ÷ 5/5 = (70/5) / (55/5) = 14/11.

Therefore, 14/55 ÷ 1/5 = 14/11.

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