Question

Observe the number line to identify the following:
(i) Number that is decomposed
(ii) The smaller numbers the above number is decomposed into.
(iii) Subtraction equation

• A. (i) 14, (ii) 4 and 10, (iii) 34 - 14 = 22
• B. (i) 34, (ii) 5 and 10, (iii) 34 - 15 = 22
• C. (i) 12, (ii) 4 and 8, (iii) 34 - 12 = 22
• D. (i) 22, (ii) 4 and 8, (iii) 34 - 22 = 12

Answer 1

The correct option is C (i) 12, (ii) 4 and 8, (iii) 34 - 12 = 22

Say:
Let’s observe the number line and identify.

Steps:

• From 34, 4 jumps are taken backward to reach 30. 34 - 4 = 30.
• From 30, 8 more jumps are taken backward to reach 22.30 - 8 = 22.
• In all, 12 jumps are taken from 34 to reach 22, by decomposing 12 into 4 and 8. 34 - 12 = 22.
• Hence, option D is the answer.
