When finding the reciprocal, it is basicaly flipping the numerator and denominator of the number. For instance, the reciporcal of 2 is 1/2, because the denominator of 2 would be 1. For an example more straight forward, the reciporacle of 3/5 is 5/3. This applied to the question goes as followed.

1. 3/5 is 5/3

2. 1/4 is 4

3. 1 is 1

Similarly when dividing fractions or an integer to a fraction, the fraction that is dividing the number turns into the reciprocal then you would multiply.

4.   3/(3/4) is 3*4/3= 4

5.   5/(3/4) is 5*(4/3)= 20/3

6.   8/(4/7) is 8*(7/3)= 56/3

7. 6/(3/5) is 6*(5/3)= 10

8. 2/(5/8) is 2*(8/5)= 16/5

9. 4/(8/9) is 4*(9/8)= 9/2

Answer:

1. \:  \:  \: \frac{5}{3}  \\

2. \:  \:  \frac{4}{1}  = 4 \\

3. \:  \:  \frac{1}{1}  = 1 \\

4. \:  \: 3 \div  \frac{3}{4}  \\  = 3 \times  \frac{4}{3}  \\  = 4 \\

5. \:  \: 5 \div  \frac{3}{4}  \\  = 5 \times  \frac{4}{3}  \\  =  \frac{20}{3}  \\  = 5 \frac{5}{3}  \\

6. \:  \: 8 \div  \frac{4}{7}  \\  = 8 \times  \frac{7}{4}  \\  = 14 \\

7. \:  \: 6 \div  \frac{3}{5}  \\  = 6 \times  \frac{5}{3}  \\  = 10 \\

8. \:  \: 2 \div  \frac{5}{8}  \\  = 2 \times  \frac{8}{5}  \\  =  \frac{16}{5}  \\  = 3 \frac{1}{5}  \\

9. \:  \: 4 \div  \frac{8}{9}  \\  = 4 \times  \frac{9}{8}  \\  =  \frac{9}{2}  \\  = 4 \frac{1}{2}  \\

Step-by-step explanation:

The question calls requires one to get the product of the given time. Since first debate lasted for :

1\frac {4}{5} \ hrs

-and the second lasted

1\frac {4}{5} hrs times more than the first then the second took then the first step will involve converting the mixed fractions into improper fraction which will be:

\frac {9}{5}

-Now multiplying

\frac {9}{5}\times\frac{9}{5}\\\\=\frac{81}{25}=3\frac{6}{25}hrs

Solve<br> 7x+2y=16<br> 5x-2y=20<br> x= y= <br><br> (3 marks)
sasho [114]
X=3 and y=-5/2. Here is why, when we do 7x+5x that gives us 12x. -2y+2y=0 and then we have 16 plus 20 which gives us 36. Now we gotta isolate x which right now we have 12x=36. Therefore divide by 12 to get x alone, which 36 divided by 12 is equal to 3. X=3. Plug it back into the equation, 7(3)=21 plus 2y=16. Subtract 21 from both sides 16-21 is equal to -5. Then 2y=-5 divide by 2 on both sides you will have -5/2=y or y=-5/2. Hope this helps!
