The question is Molly knows that 45 * 811 = 36,495

Use this understanding to help Molly solve 4.5 * 81.1

Choose 1

a 364,950

b 3,649.5

c 364.95

d 36.495

C

Step-by-step explanation:

4.5 is 45 ÷ 10 and 81.1 is 811 ÷ 10 so that means that 4.5 × 81.1 = 45 ÷ 10 × 811 ÷ 10 = (45 × 81) ÷ 100. We know that 45 × 81 = 36,495 so we just have to divide that by 100 to get 364.95.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
