Answer:
To find out how many 2/5 meter pieces Sven can cut off from a board that is 9/10 meters long, we need to divide the length of the board by the length of each piece.
We can convert the mixed number 2/5 to an improper fraction by multiplying the whole number 1 by the denominator 5 and adding the numerator 2, giving us 7/5.
Then, we can divide the length of the board, which is 9/10 meters, by the length of each piece, which is 7/5 meters:
(9/10) ÷ (7/5)
To divide by a fraction, we can multiply by its reciprocal:
(9/10) x (5/7)
Simplifying the fractions:
(9 x 5) / (10 x 7) = 45 / 70
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 5:
(45/5) / (70/5) = 9/14
Therefore, Sven can cut off 9 pieces that are 2/5 meters long from a board that is 9/10 meters long.
Explanation:
the simple answer is that Sven can cut off 9 pieces that are 2/5 meters long from a board that is 9/10 meters long.
