<em><u>Question:</u></em>
A jeweler is dividing 3/8 of a pound of rubies among 4 lots. What part of a pound will each lot weigh? A.1/4 B.1/8 C.1/16 D.3/32
<em><u>Answer:</u></em>
Option D
Each lot weight 
part of pound
<em><u>Solution:</u></em>
Given that,
A jeweler is dividing 3/8 of a pound of rubies among 4 lots
To find: part of a pound each lot weigh
From given,
Let "x" be the part of a pound each lot weigh
Therefore,
This forms a proportion and solve by cross multiplying
Thus, each lot weight part of pound

Answer:
what do you have to do... do you have to find the slope of them????
3.9 can be rounded to 4.
5.3 can be rounded to 5.
4 x 5 = 20
That tells you that 3.9 x 5.3 has a digit in the tens place.
Then you can proceed to multiply 39 and 53, which equals 2067.
(Note: I removed the decimals on purpose)
Now we know that in 2067, the 2 should be in the tens place. That means 0 is in the ones place and that 6 is in the tenths place. That leaves 7 to be in the hundreths place.
Therefore, 3.9 x 5.3 = 20.67
Answer: the answer is 521
