To find the product of a reasonable estimate of two decimal numbers, round each decimals to the nearest whole number and then perform the multiplication.
For example:
3.2 x 5.7
Estimated answer
3.2 will be rounded down to 3 and 5.7 will be rounded up to 6
⇒ 3 x 6 = 18
Actual Answer
3.2 x 5.7
=18.24
<span>9*45
= 9(40 + 5)

Answer:
12.66 
Step-by-step explanation:
Given the dimensions of the room are 
=
and 
=
.
The area of the room =
Area=
Area=72.33
The area of the carpet=85
The area of carpet left= Total area of carpet - the area of the room
The area of carpet left= 85-72.33=12.66
One of the ways to find the answer is to find how much 1 percent of 150 is. To do that we just have to divide 150 by 100:
150 / 100 = 1.5
Now we can divide 9 by 1.5 to know how much percent of 150 it is:
9 / 1.5 = 6
Let's check it:
150 * 6% = 150 * 6/100 = 15 * 6/10 = 3 * 6/2 = 18/2 = 9
It's correct then :)
