Question

12. Fill in the blanks :

(a) Comparing two same quantities by division is called ___.

(b) A ratio is always expressed in ___ form.

(c) The first term of a ratio 11:24 is ___ and the second term is ___.

(d) The ratio of the letter 'M' in the word MATHEMATICS to the total letters in the word is ___.

(e) The ratio of even number to odd number in a set of natural numbers from 1 to 25 is ___.

ANSWER :

(a) Comparing two same quantities by division is called ratio.

(b) A ratio is always expressed in simplest form.

(c) The first term of a ratio 11:24 is 11 and the second term is 24.

(d) The ratio of the letter 'M' in the word MATHEMATICS to the total letters in the word is 2:11.

(e) The ratio of even number to odd number in a set of natural numbers from 1 to 25 is 12:13.

Answer 2

Answer :

(a) Ratio

(b) Simplest

(c) 11, 24

(d) 2 : 11

(e) 12 : 13

Step-by-step explanation :

(a) Comparing two same quantities by division is called Ratio.

(b) A ratio is always expressed in simplest form.

(c) The first term of a ratio 11:24 is 11 and the second term is 24.

(d) The ratio of the letter 'M' in the word MATHEMATICS to the total letters in the word is 2 : 11

⇒ Total words = 11

⇒ No of M = 2

Ratio = 2 / 11

Ratio = 2 : 11

(e) The ratio of even number to odd number in a set of natural numbers from 1 to 25 is 12 : 13

No of evens = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24

Total evens = 12

Total odds = 25 - 12 = 13

Ratio = 12 : 13
