Mrs Rama uses 0.4 liters of water melon juice for every 0.9 liters of apple juice to make a jug of mixed fruit juice.

A) Find the ratio of the amount of watermelon juice to the amount of apple juice.
B) For every 225 ml of apple juice, how much watermelon juice should Mrs Rama use?
C) If Mrs Rama uses 80 ml of watermelon juice, how much apple juice does she need?

apple juice --- a

watermelon juice --- w

a : w = .4 : .9 = 4 : 9

B) 225/w = 4/9
4w = 9(225)
w = 506.25

C) a/80 = 4/9
9a = 320
a = 35.55..

A) To find the ratio of watermelon juice to apple juice, we need to divide the amount of watermelon juice by the amount of apple juice.

Given: Mrs Rama uses 0.4 liters of watermelon juice for every 0.9 liters of apple juice.

The ratio is calculated as follows:
Ratio = Amount of Watermelon Juice / Amount of Apple Juice.

So, the ratio is 0.4 liters / 0.9 liters, which simplifies to 4/9.

Therefore, the ratio of the amount of watermelon juice to the amount of apple juice is 4:9.

B) To find the amount of watermelon juice for a given amount of apple juice, we can use the ratio we found in part A.

Given: For every 225 ml of apple juice, we need to find how much watermelon juice Mrs Rama should use.

Step 1: Calculate the equivalent ratio for 225 ml of apple juice using the ratio found in part A.

Ratio = Amount of Watermelon Juice / Amount of Apple Juice = 4/9

Since the ratio is in liters, convert 225 ml to liters: 225 ml / 1000 = 0.225 liters.

Step 2: Multiply the equivalent ratio by the amount of apple juice.

Watermelon Juice = Ratio x Amount of Apple Juice
Watermelon Juice = (4/9) x 0.225 liters

Calculating this expression gives us: Watermelon Juice = 0.1 liters.

Therefore, for every 225 ml of apple juice, Mrs Rama should use 0.1 liters of watermelon juice.

C) To find how much apple juice Mrs Rama needs, given a specific amount of watermelon juice, we can use the ratio found in part A.

Given: Mrs Rama uses 80 ml of watermelon juice.

Step 1: Calculate the equivalent ratio for 80 ml of watermelon juice using the ratio found in part A.

Ratio = Amount of Watermelon Juice / Amount of Apple Juice = 4/9

Step 2: Rearrange the formula to solve for the Amount of Apple Juice.

Amount of Apple Juice = Amount of Watermelon Juice / Ratio

Amount of Apple Juice = 80 ml / (4/9)

Calculating this expression gives us: Amount of Apple Juice = 180 ml.

Therefore, if Mrs Rama uses 80 ml of watermelon juice, she will need 180 ml of apple juice.
