if you have a 6 foot long board and it's cut into 4/5 pieces how many pieces can you have a what portion of the board is left over
Is each piece 4/5 of a foot long?
7 Boards that are 9.6" each and you have 2/5 remaining or 4.8"
IDK THIS IS RLY HARD!!!
To find out how many pieces you can have when you cut a 6-foot-long board into 4/5 pieces, you need to divide the total length of the board by the length of each piece.
The length of each piece can be calculated by dividing the total length (6 feet) by the number of pieces (4/5). To divide by a fraction, you need to multiply by its reciprocal. So, in this case, you can rewrite the division as 6 * (5/4).
Calculating this gives you:
6 * (5/4) = 30/4 = 7.5 feet
Therefore, each piece would be 7.5 feet long.
To determine how many pieces you can have, divide the total length of the board (6 feet) by the length of each piece (7.5 feet).
6 / 7.5 = 0.8
Since you can't have fractional pieces, you can have a maximum of 0.8 pieces. However, since this doesn't make practical sense, you would usually round down to the nearest whole number. Therefore, in this case, you can have a maximum of 0 pieces or 1 piece.
As for the portion left over, you can find it by subtracting the total length of the pieces from the total length of the board:
6 feet - (7.5 feet * 1 piece) = 6 - 7.5 = -1.5 feet
The negative value indicates that there is not enough board length to cut any more pieces. Hence, there would be no portion left over in this scenario.
