All you'd have to do is multiply 20 cm2 by 5 cm because volume is cm3, so if the base is already giving you cm2, you'll need the last measure which is height.
The answer would be 100 cm3
The basic idea is that multiplying by 10 just moves the decimal point one place to the right. It makes the number bigger.
Examples:
3.1 x 10 = 31
3.1 x 10 x 10 = 31 x 10 = 310
Each time you multiply by another 10, the decimal point moves one more place.
In your exercise, says you're going to multiply by 10 <u>three</u> times in a row. So that will move the decimal point 3 places to the right.
So what do you get if you move the decimal in 4.25 three places to the right?
I believe the answer is x=0
The answer is 3 losses, or choice B.
Pay attention to the ratios. Each one has a ratio of 9:1.
27/9 is 3. 27:3 is the same as 9:1.
So 3 losses
