**Do the ratios form a proportion worksheet :**

Here we are going to see some practice questions of the topic "Do the ratios form a proportion worksheet".

(1) State if the following pair of ratios forms a proportion

4/2 and 20/6

(2) State if each pair of ratios forms a proportion

6/9 and 2/3

(3) State if each pair of ratios forms a proportion

4/3 and 16/12

(4) State if each pair of ratios forms a proportion

12/24 and 3/4

(5) State if each pair of ratios forms a proportion

4/3 and 8/6

- Compare the given fractions with the fractions a/b and c/d.
- Multiply the values which are in the places of "a" and "d"
- Multiply the values which are in the places of "b" and "c"
- Check whether the value of ad is equal to bc.
- If yes, then we say that the two fractions are in proportion.
- Otherwise they are not in proportion.

Let us see some example problems based on the above concept.

**Question 1 :**

State if the following pair of ratios forms a proportion

4/2 and 20/6

**Solution : **

**Step 1 :**

**Comparing the first fraction 4/2 with a/b and the second fraction 20/6 with c/d.**

**Step 2 :**

**a = 4, b = 2, c = 20 and d = 6.**

**Step 3 :**

**ad = 4(4), bc = 2(20)**

**ad = 16, bc = 40**

**Step 4 :**

**ad **≠ **bc**

**Hence the given fractions will not form a proportion.**

**Question 2 :**

State if each pair of ratios forms a proportion

6/9 and 2/3

**Solution : **

**Step 1 :**

**Comparing the first fraction 6/9 with a/b and the second fraction 2/3 with c/d.**

**Step 2 :**

**a = 6, b = 9, c = 2 and d = 3**

**Step 3 :**

**ad = 6(3), bc = 9(2)**

**ad = 18, bc = 18**

**Step 4 :**

**ad = ** **bc **

**Hence the given fractions form a proportion.**

**Question 3 :**

State if each pair of ratios forms a proportion

4/3 and 16/12

**Solution : **

**Step 1 :**

**Comparing the first fraction 4/3 with a/b and the second fraction 16/12 with c/d.**

**Step 2 :**

**a = 4, b = 3, c = 16 and d = 12**

**Step 3 :**

**ad = 4(12), bc = 3(16)**

**ad = 48, bc = 48**

**Step 4 :**

**ad = ** **bc **

**Hence the given fractions form a proportion.**

**Question 4 :**

State if each pair of ratios forms a proportion

12/24 and 3/4

**Solution : **

**Step 1 :**

**Comparing the first fraction 12/24 with a/b and the second fraction 3/4 with c/d.**

**Step 2 :**

**a = 12, b = 24, c = 3 and d = 4**

**Step 3 :**

**ad = 12(4), bc = 24(3)**

**ad = 48, bc = 72**

**Step 4 :**

**ad **≠** ** **bc **

**Hence the given fractions will not form a proportion.**

**Question 5 :**

State if each pair of ratios forms a proportion

4/3 and 8/6

**Solution : **

**Step 1 :**

**Comparing the first fraction 4/3 with a/b and the second fraction 8/6 with c/d.**

**Step 2 :**

**a = 4, b = 3, c = 8 and d = 6**

**Step 3 :**

**ad = 4(6), bc = 3(8)**

**ad = 24, bc = 24**

**Step 4 :**

**ad =**** ** **bc **

**Hence the given fractions form a proportion.**
