Answer:
n ≥ 1/4
Step-by-step explanation:
I wish I could add a picture, but I can't, so you'll have to graph it by yourself.
983.625
9 = hundreds
8 = tens
3 = ones
6 = tenths
2 = hundredths
5 = thousandths
You want to round to the nearest hundredths
Look at the number on the right, if it's bigger than 5, round up, if it's 4 or lower, round down.
In this case, the number to the right is a 5, so you round the 2 (hundredths) up one so:

Answer:
(a) 0.018 dm^3
(b) 20 x 10^15 ml^3
Step-by-step explanation:
a) 18 cm^3 to dm^3
1 cm = 0.1 dm
So,
1 cm^3 = 0.001 dm^3
So, 18 cm^3 = 18 x 0.001 dm^3 = 0.018 dm^3
b) 20 hl^3 to ml^3
1 hl = 100000 ml
So, 1 hl^3 = 10^15 ml^3
So,
20 hl^3 = 20 x 10^15 ml^3.
Answer:
163/40
Step-by-step explanation:
Imroper fraction: Numerator > denomenator.
It is 4 + 0.075. so you need to find what 0.075 is as a fraction.
To go decimal -> fraction, multiply by 10/10, 100/100, 1000/1000 etc. until it is a whole number on top.
0.075 *(1000/1000) = 75 / 1000
Then simplify. (Divide top and bottom by 25)
3 / 40
Now convert 4 to over 40, by doing 4 * 40 / 40 = 160 / 40.
Then add 3 / 40 + 160 / 40 = 163/40
