Answer:

1. 1/2

2. 3/4

3. 1/6

4. 1/4

5. 7/4

6. 3/2

7. 5/1

8. 2/7

9. 1/4

Step-by-step explanation:

A ratio compares values.

So if there are 3 oranges and 12 apples, we can say that there is a ratio of 3 : 12 meaning there are 3 oranges for every 12 apples.

Ratios can be written in different ways, but they mean the same thing:

  • Using the ":" to separate the values:                     3 : 12
  • Or using the word "to" to separate the values:   3 to 12
  • or as a fraction:                                                          \frac{3}{12}

A ratio can also be scaled up or scaled down (as long as we do the same thing to both values):

  • 3 : 12  is the same as 6 : 24  (multiplied both values by 2)
  • 3 : 12  is the same as 1 : 4  (divided both values by 3)

1.  2 to 4  = 2 : 4 = 2/4

We can reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 2:  2/4 = 1/2

2. 15/20

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 5:

15/20 = 3/4

3. 6 : 18 = 6/18

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 6:

6/18 = 1/6

4. 3 to 12 = 3 : 12 = 3/12

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 3:

3/12 = 1/4

5. 7 : 4 = 7/4

This fraction cannot be reduced any further as the numerator is a prime number.  Prime numbers are whole number greater than 1 that cannot be made by multiplying other whole numbers.

6. 18/12

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 6:

18/12 = 3/2

7. 35 : 7 = 35/7

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 7:

35/7 = 5/1  

(5/1 = 5 however the question is asking you to write the ratio in the lowest fraction, so the lowest fraction is 5/1)

8. 8/28

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 4:

8/28 = 2/7

9. 24 : 96 = 24/96

Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 24:

24/96 = 1/4

Find constants a and b such that the function y = a sin(x) + b cos(x) satisfies the differential equation y'' + y' − 7y = sin(x)
Elza [17]
The first thing we must do in this case is find the derivatives:
 y = a sin (x) + b cos (x)
 y '= a cos (x) - b sin (x)
 y '' = -a sin (x) - b cos (x)
 Substituting the values:
 (-a sin (x) - b cos (x)) + (a cos (x) - b sin (x)) - 7 (a sin (x) + b cos (x)) = sin (x)
 We rewrite:
 (-a sin (x) - b cos (x)) + (a cos (x) - b sin (x)) - 7 (a sin (x) + b cos (x)) = sin (x)
 sin (x) * (- a-b-7a) + cos (x) * (- b + a-7b) = sin (x)
 sin (x) * (- b-8a) + cos (x) * (a-8b) = sin (x)
 From here we get the system:
 -b-8a = 1
 a-8b = 0
 Whose solution is:
 a = -8 / 65
 b = -1 / 65
 Answer:
 
constants a and b are:
 
a = -8 / 65
 
b = -1 / 65
