Question

write each ratio, use words, a colon, or a fraction

3/4 , 9/12
1/3 , 2/9
3/5 , 6/10
4/6 , 8/12

Answer 1

The answers are given below.

Step-by-step explanation:

$\frac{3}{4}, \frac{9}{12} = 3 : 4 : : 9 : 12\\\\\frac{1}{3}, \frac{2}{9} = 1 : 3 : : 2 : 9\\\\\frac{3}{5}, \frac{6}{10} = 3 : 5 : : 6 : 10\\\\\frac{4}{6}, \frac{8}{12} = 4 : 6 : : 8 : 12$

Hence, the above expressions are answers.

Answer 2

Given:

(i) Ratios are supplied as:

3/4 , 9/12  , 1/3 , 2/9  , 3/5 , 6/10  , 4/6 , 8/12

To find:

(i) Express these ratios as

(a) Words

(b) Colon

(c) Fraction

Solution:

Ratios are expressed in words with the help of 'is to'.

For example,

a/b is written as 'a is to b' in words and,

a/b = a:b by using colon

So, 3/4 = 3 is to 4 in words and 3:4

9/12 = 9 is to 12 in words and 9:12 or 3:4 in simplified terms.

1/3 = 1 is to 3 in words and 1:3

2/9 = 2 is to 9 in words and 2:9

3/5 = 3 is to 5 in words and 3:5

6/10 = 6 is to 10 in words and 6:10 or 3:5 in simplified terms.

4/6 = 4 is to 6 in words and 4:6 or 2:3 in simplified terms.

8/12 = 8 is to 12 in words and 8:12 or 2:3 in simplified terms.
