The ratio of the blue markers to red markers is 3:7. If there are 40 total markers in the bucket,how many of the markers will be blue
3/10 = x/40
Cross multiply and solve for x.
To find the number of blue markers, we first need to determine the multiplier that will scale the ratio between blue markers and red markers.
The ratio of blue markers to red markers is 3:7. This means that for every 3 blue markers, there are 7 red markers.
To determine the multiplier, we add the two parts of the ratio: 3 + 7 = 10.
Since we have a total of 40 markers in the bucket, we divide the total number of markers by the multiplier:
40 / 10 = 4
Now that we have the multiplier, we multiply it by the number of blue markers in the ratio:
3 * 4 = 12
Therefore, there will be 12 blue markers in the bucket.
