Rewrite the expression 9(6 + 5) as the sum of 54 and another whole number.
lisabon 2012 [21]

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.
