Answer:
45 is the other whole number.
Step-by-step explanation:
Method I:
Given: 9(6 + 5)
Distribute 9 over 6 and 5. We get:
9 X 6 + 9 X 5 = 54 + 45
⇒ 45 should be added to 54 to arrive at the sum.
Method 2:
Given: 9(6 + 5)
⇒ 9 X 11 [Since, 6 + 5 = 11]
= 99
Therefore, 99 = 54 + a
⇒ a = 99 - 54
⇒ a = 45
Hence, the other number is 45.
