Given:
Amount of drops of yellow dye = 18
Amount of drops of blue dye = 12
Total drops = 18 + 12 = 30
Let's find the ratio of drops of blue drops to total drops.
Ratio can be said to be how many times a number contains another number. It is used to compare values.
Ratio of A to B is written as==> A : B
To find the ratio of blue to yellow, we have:
Ratio of blue to yellow = Amount of blue drops : Amount of total drops
Ratio of blue to yellow = 12 : 30
Simplify the ratio by dividing the numbers by the Greates Common Factor(GCF).
GCF of 12 and 30 = 6
Thus, we have:
[tex]\begin{gathered} 12^{}\div6\colon30\div6 \\ \\ =2\colon5 \end{gathered}[/tex]Therefore, the ratio of blue drops to the total drops is = 2:5
ANSWER:
[tex]2\colon5[/tex]
