Easy Way to Divide By 9


Easy Way to Divide By 9

23 / 9 = 2 remainder 5

The first figure of 23 is 2, and this is the answer.

The remainder is just 2 and 3 added up!
43 / 9 = 4 remainder 7

The first figure 4 is the answer
and 4 + 3 = 7 is the remainder - could it be easier?

Divide by 9:

1)  61 / 9 =    wpe4.jpg (1664 bytes)    remainder     wpe4.jpg (1664 bytes)   

2)  33 / 9 =    wpe4.jpg (1664 bytes)    remainder     wpe4.jpg (1664 bytes)

3)  44 / 9 =    wpe4.jpg (1664 bytes)   remainder      wpe4.jpg (1664 bytes)

4)  53 / 9  =   wpe4.jpg (1664 bytes)    remainder     wpe4.jpg (1664 bytes)

5)  80 / 9  =   wpe4.jpg (1664 bytes)    remainder     wpe4.jpg (1664 bytes)


In 134 / 9 = 14 remainder 8
The answer consists of 1,4 and 8.

1 is just the first figure of 134.

4 is the total of the first two figures 1+ 3 = 4,
and 8 is the total of all three figures 1+ 3 + 4 = 8.

Divide by 9:

1)  232 =      wpe4.jpg (1664 bytes)    remainder     wpe4.jpg (1664 bytes)

2)  151 =      wpe4.jpg (1664 bytes)    remainder     wpe4.jpg (1664 bytes)

3)  303 =      wpe4.jpg (1664 bytes)   remainder      wpe4.jpg (1664 bytes)

4)  212 =      wpe4.jpg (1664 bytes)    remainder      wpe4.jpg (1664 bytes)

5)  2121 =  wpe4.jpg (1664 bytes)    remainder      wpe4.jpg (1664 bytes)

842 / 9 = 812 remainder 14 = 92 remainder 14

Actually a remainder of 9 or more is not usually
permitted because we are trying to find how
many 9's there are in 842.

Since the remainder, 14 has one more 9 with 5
left over the final answer will be 93 remainder 5

Divide these by 9:

1)  771 / 9  =      wpe4.jpg (1664 bytes)    remainder   wpe4.jpg (1664 bytes)
2)  942 / 9  =      wpe4.jpg (1664 bytes)    remainder   wpe4.jpg (1664 bytes)
3)  565 / 9 =       wpe4.jpg (1664 bytes)    remainder   wpe4.jpg (1664 bytes)
4)  555  / 9 =      wpe4.jpg (1664 bytes)    remainder   wpe4.jpg (1664 bytes)
5)  2382 / 9  =    wpe4.jpg (1664 bytes)    remainder   wpe4.jpg (1664 bytes)
6)  7070 / 9  =    wpe4.jpg (1664 bytes)    remainder   wpe4.jpg (1664 bytes)
