Question

22 bottles of ketchup are distributed as samples. A few more bottles are yet to be distributed. Observe the number line to identify the number of bottles yet to be distributed. Choose the subtraction equation for the problem.

• A. 68, 68 - 22 = 46
• B. 68, 68 - 22 = 47
• C. 22, 68 - 46 = 22
• D. 46, 68 - 22 = 46

Answer 1

The correct option is D 46, 68 - 22 = 46

Say:
Let’s observe the number line and the given information to identify the number of bottles left to be delivered. Choose the correct subtraction equation.

Steps:

• Number of bottles distributed for free = 22.
• On the number line, the backward jumps taken are shown from 68.
• Hence, the total number of bottles = 68.
• To find the number of bottles left to be delivered, we subtract 68 - 22.
• As per the number line, 22 is broken apart into 8 and 14.
• From 68, 8 backward jumps are taken, reaching 60.
• 68 - 8 = 60.
• From 60, 14 more backward jumps are taken, reaching 46.
• 60 - 14 = 46.
• Therefore, the number of bottles left to be delivered = 46.
• Hence, option B is the answer.
