Question

gina has a box of red blue and green markers. The ratio of the number of red markers to the number blue markers is 5:2. The ratio of the number of blue Markers to the number of green markers is 3:5. what is the ratio of the number of red markers to the number of green markers?

Answer 1

Answer:

Required ratio is 5:1

Step-by-step explanation:

We have been given The ratio of the number of red markers to the number blue markers is 5:2. The ratio of the number of blue Markers to the number of green markers is 3:5.

We have to find the ratio of number of red markers  to the number of green markers.

$\frac{\text{red markers}}{\text{blue markers}}=\frac{5}{2}$

$\frac{\text{blue Markers}}{\text{green markers}}=\frac{3}{5}$

To find ratio of red to green marker we will do the following:

$\frac{\text{red marker}}{\text{green marker}}=\frac{\frac{\text{red marker}}{\text{blue marker}}}{\frac{\text{blue marker}}{\text{green marker}}}$

$\frac{\text{red marker}}{\text{green marker}}=\frac{\frac{5}{2}}{\frac{3}{5}}=$

$\frac{\text{red marker}}{\text{green marker}}=\frac{5}{1}$

Hence, the required ratio is  5:1

Answer 2

This can be solve by cancel of units

Snice red/ bkue = 5/2

And bkue/ green = 3/ 5

So red/ green = (red/ bkue) x( blue/ green)

Red/ green = (5/ 2) x (3/ 5)

Red / green = 3 /2

So the ratio of red is to green is 3: 2
