Why is 9 maximum number of beads on abacus?
The number 9 is the maximum number of beads on an abacus because it is the last number in the ones place before the tens place is reached.. The abacus is a tool that was used for arithmetic in ancient times. It is composed of a frame with a series of rods or wires on which beads are strung. The beads are used to represent numbers.
How many 4mm beads fit in a 16 inch strand?
There are exactly 25.4 mm for each inch. Therefore, there are 16*25.4=406.4 mm in 16 inches. Assuming that 4 mm beads occupy exactly 4 mm along the length, this would allow 406.4/4=101.6 beads to occupy that length. In other words, you would have 101 beads but only 6/10=3/5 of a bead until you got to the 16 inch mark. Thus the answer is 101 whole beads with a little bit left over given the assumption about bead length.As a practical matter, the above calculation assumes that the beads are to occupy the entire "strand" and that the length given is not the entire length of the beading string itself, which would be longer in order to tie it. if the beads are actually a little shorter than 4mm or they don't have to be aligned along the length of the beading string exactly, you might be able to get 102 or more beads "along" the length.Read more: How_many_8mm_beads_in_16_inches
