Question

How do I answer A and B?

Answer 1

Answer:

Step-by-step explanation:

a) We're working with the ratio 3:1

x:500

500/1 = 500

500 * 3 = 1,500

x = 1,500

She would need to use 1,500 mL of yellow ink.

b) We're working with the ratio 2:3

x:750

750/3 = 250

250 * 2 = 500

x = 500

She would need to use 500 mL of red ink.

You can check both of these by:

(a) 1,500/500 = 3/1 = 3 : 1 which is the ratio we're working with.

(b) 500/2 = 250

750/2 = 375

250 : 375

Then, divide both 250 and 375 by 125

250/125 = 2

375/125 = 3

We are then left with the ratio 2 : 3 which is the ratio we're working with.
