Decrease 1,000 in the ratio 4: 5
To decrease 1,000 in the ratio 4:5, we first need to find the total number of parts in the ratio which is 4 + 5 = 9.
Next, we calculate the value of each part by dividing the total decrease (1,000) by the total number of parts: 1,000 / 9 = 111.11 (approx).
Now, we calculate the decrease for each part by multiplying the value of each part by the ratio value:
4 parts = 4 * 111.11 = 444.44 (approx)
5 parts = 5 * 111.11 = 555.55 (approx)
Therefore, the decrease for the ratio 4:5 is 444.44 and 555.55 respectively.
