Answer:
A reasonable estimate is [tex]1,900 * 300 = 570,000[tex]
Step-by-step explanation:
This is because 1,900 is the closest multiple of 100 for 1,912, and 300 is the closest multiple of 100 for 305. And [tex]1,900 * 300[tex] is [tex]19 * 3 * 10,000[tex].
Ok so
Knowing that 1 metre consists of 100cm,
You can conclude and agree that 8 cm is 8/100, correct?
Now, when converting fractions to decimals, it makes it easier out of 100 or 10. Since it's out of 100 already, you take the amount of zero's in 100 (two) and you move the decimal point (2) places to the <em /><u>left<em /></u>
This gives you 0.08
So the fraction is 8/100, which then can be simplified to 4/50, then to 2/25
and the decimal is 0.08.
It is a right triangle because of the square on the bottom left which represents a 90 degree angle.
Hope this helps.
