This is my thinking;
To convert meters to kilometers, in decimals, its 0.001. So converting that into kilometers, that would be 0.057
16 of his stamps are from Africa, since 1/4 of 64 is 16. If I subtract his 28 from Europe and Africa (16 plus 12 equals 28) from his original 64, I am left with 36 stamps. 36/64 is simplified to 9/16. So 9/16 of Terrence's stamps are from Asia.
Answer:
Step-by-step explanation:
Writing out the word question in numbers: three tenths plus thirty nine hundredths equals blank -
3/10 + 39/100 = ?
= 30/100 + 39/100
= 69/100
or 0.69 or sixty nine hundredths.

Liz wants to find the quotient of 63 and 0.15. what is the first step she should take?
Answer:
→(Well First 63 ÷ 0.15 = 420) ←
A: divide 63 and 0.15 by 10 Would be my Answer
To add two decimal numbers, first check if they have the same number of digits to the right of the decimal point. If they don't, add zeros to the right of one of the numbers until they do. Then, write one number on top of the other, lining up the decimal points vertically.

Answer: y= -3x
(there is no y-intercept in the points you listed so if you can find one on a picture of your question, do so. but since i do not see a given y-intercept, i assume it is 0)
To find the slope, use the two points given.
1st: subtract the y-values. 0-6= -6.
2nd: subtract the x-values. 0-(-2)= 2
3rd: you have -6/2.
4th: simplify to get a slope of -3.
