Question

4/5÷8 = ; 5/6÷10=; 3/7÷12=; 4÷2/5=;21÷7/8=; 25÷5/8=;1/8÷3/4=.

Answer 1

Ответ:

4/5:8=1/10; 5/6:10=1/12; 3/7:12=1/28; 4:2/5=10; 21:7/8=24; 25:5/8=40; 1/8:3/4=1/6

Пошаговое объяснение:

1. 4/5:8= 4/5:8/1= 4/5*1/8=4/40=1/10

2. 5/6:10= 5/6:10/1= 5/6*1/10= 5/60=1/12

3. 3/7:12= 3/7:12/1= 3/7*1/12= 3/84=1/28

4. 4:2/5= 4/1:2/5= 4/1*5/2= 20/2=10

5. 21:7/8= 21/1:7/8= 21/1*8/7=168/7=24/1=24

6. 25:5/8= 25/1:5/8= 25/1*8/5= 200/5=40/1=40

7. 1/8:3/4= 1/8*4/3= 4/24= 1/6

Answer 2

To solve these division problems involving fractions, you can remember that dividing by a fraction is the same as multiplying by its reciprocal (flipping the fraction and multiplying). Here are the solutions to each of your equations:

1. (4/5) ÷ 8 = (4/5) * (1/8) = (4/40) = 1/10

2. (5/6) ÷ 10 = (5/6) * (1/10) = (5/60) = 1/12

3. (3/7) ÷ 12 = (3/7) * (1/12) = (3/84) = 1/28

4. 4 ÷ (2/5) = 4 * (5/2) = 20/2 = 10

5. 21 ÷ (7/8) = 21 * (8/7) = 168/7 = 24

6. 25 ÷ (5/8) = 25 * (8/5) = 200/5 = 40

7. (1/8) ÷ (3/4) = (1/8) * (4/3) = (4/24) = 1/6
