A ratio can be simplified by dividing both sides of the ratio by the Highest Common Factor (HCF). The highest common factor is the largest number that goes into both numbers of your ratio. In example 1 you are asked to simplify the ratio 6:8. Here the HCF is 2 so divide both sides of the ratio by 2 to give 3:4.

Ratios are like fractions: to make an equivalent ratio you simply multiply both sides of the ratio by the same non-zero number. 1:2 is equivalent to 2:4 (both sides multiplied by 2). 10:12 is equivalent to 5:6 (both sides multiplied by 1/2).

Let m represent the subscription rate for a man, and w the subscription rate for a woman.

m/w=4/3, or** m=(4/3)w**.

2 men and 5 women paid 460. Thus

**2m+5w=460.**

Substitute**(4/3)w** for **m**, in **2m+5w=460**.

This gives an equation in the unknown w. Solve for w

2(4/3)w +5w=460 or (23/3)w=460.**Answer is w=60**

Use this value in the relation m=(4/3)w to get m=80.

**Check m/w=80/60=4/3**

m/w=4/3, or

2 men and 5 women paid 460. Thus

Substitute

This gives an equation in the unknown w. Solve for w

2(4/3)w +5w=460 or (23/3)w=460.

Use this value in the relation m=(4/3)w to get m=80.

the ratio you are working with is 2/5

For every 2 Egg buyer there is 5 Plain buyer

A2/5=number of Egg buyers OR

A5/2=number of Plain buyers

Since the question asks for "how many Plain buyers" Use the second formula.

Example...10=A (number of Egg buyers)

10 x 5/2=25

10 buyers of egg = 25 buying plain

For every 2 Egg buyer there is 5 Plain buyer

A2/5=number of Egg buyers OR

A5/2=number of Plain buyers

Since the question asks for "how many Plain buyers" Use the second formula.

Example...10=A (number of Egg buyers)

10 x 5/2=25

10 buyers of egg = 25 buying plain

To solve this, you need to multiply the ratios together.

(2/5)*(3/4) = A/C

So (2*3)/(5*4) = A/C

6/20 = A/C

You can reduce that be dividing both sides by 2

3/10 = A/C

Here is an example:

Let X = 3

The problem states that A/B = 2/5

So let A = 2X & B = 5X

A = 2*(3) = 6

B = 5*(3) = 15

Now check the ratio: 6/15 = 2/5. The same as what was given.

Now lets look at the ratio for B/C. The given ratio for B/C was 3/4

Using the value of B that we just solved we get:

B = 15

C = (4/3)*15 = 20

Check the ratio.

15/20 = 3/4

Now we have the values for each of the variables

A = 6

B = 15

C = 20

The ratio of A/C is 6/20

6/20 can be reduced to 3/10 be dividing both numbers by 2

(2/5)*(3/4) = A/C

So (2*3)/(5*4) = A/C

6/20 = A/C

You can reduce that be dividing both sides by 2

3/10 = A/C

Here is an example:

Let X = 3

The problem states that A/B = 2/5

So let A = 2X & B = 5X

A = 2*(3) = 6

B = 5*(3) = 15

Now check the ratio: 6/15 = 2/5. The same as what was given.

Now lets look at the ratio for B/C. The given ratio for B/C was 3/4

Using the value of B that we just solved we get:

B = 15

C = (4/3)*15 = 20

Check the ratio.

15/20 = 3/4

Now we have the values for each of the variables

A = 6

B = 15

C = 20

The ratio of A/C is 6/20

6/20 can be reduced to 3/10 be dividing both numbers by 2

15 men earns 525

1 man raens 525/15

equals to 35

7 women earns 525

1 women earns 75

so 7 men and 13 women earns 7 *35+13*75=245+975=1220

1 man raens 525/15

equals to 35

7 women earns 525

1 women earns 75

so 7 men and 13 women earns 7 *35+13*75=245+975=1220
