what is the base 7 number for 143 in base 10?

Question

i need to know how to do it also

Answer 1

Ok, in base 10 we have placeholders for ones, tens, hundreds etc. In base 7 we have placeholders but they are ones, sevens, forty-nines, etc.

There are 2 forty-nines in 143 so a 2 goes in the forty-nine placeholder. You have a remainder of 45.

There are 6 sevens in 45. So 6 goes in the sevens place. There is a remander of 3. The 3 goes in the ones spot.

So the answer is 263 (base 7)

Answer 2

143 in base 10 is written in units , tens and hundreds.

to express it in base 7, you have to write the number in units, sevens, forty nines and .....(with luck, we won't have to work this out = 7^3)

You start with a long division

49 into 143 goes twice remainder45

write the 2 in the forty nines column and divide 7 into 45

7 into 45 goes 6 times remainder 3

write the 6 in the sevens column and the 3 in the units column.

143 in base 10 = 263 in base 7

Answer 3

143 = (2 x 49)+ (6x 7)+3
this is 2 x 7^2 + 6 x 7^1 + 3

or 263

Answer 4

Just start the series of counting over when you get to 6; instead of writing '7', write '10.' 14 in base 10 = 20 in base 7.
Hope this helps~

Answer 5

143 in base 10 (1 x100 + 4x10 + 3x1) = 263 (2x49 + 6x7 + 3x1)

Note: Your phrasing makes it hard to tell if 143 is in base 10 or base 7; try to phrase it so we know where we're starting:
what is the "base 7 number for 143" in base 10?
what is the base 7 number for "143 in base 10"?

Answer 6

Here's how it's done:
Divide 143 by 7 repeatedly. Put down the
remainder each time. Stop when you get a
quotient less than 7.We get
...............143
..............20 3
.............2 6 3

Since the last quotient is less than 7, we can stop.
The answer is 263.

Answer 7

143 base 7 = 1*7^2 + 4*7 + 3 = 80
