In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If
Vesna [10]

Answer:

Cranberry:Apple:Orange = 7:5:8

Step-by-step explanation:

Given

Apple = 1/4

Orange = 2/5

Required

Determine the ratio of Cranberry to Apple to Orange

First, we calculate the fraction of Cranberry using:

Cranberry + Apple + Orange = 1

Substitute values for Apple and Orange

Cranberry + 1/4+ 2/5= 1

Collect Like Terms

Cranberry = 1- 1/4- 2/5

Take LCM

Cranberry = \frac{20 - 5 - 8}{20}

Cranberry = \frac{7}{20}

The ratio is then represented as:

Cranberry:Apple:Orange = 7/20:1/4:2/5

Multiply through by 20

Cranberry:Apple:Orange = 20(7/20:1/4:2/5)

Cranberry:Apple:Orange = 20*7/20:20*1/4:20*2/5

Cranberry:Apple:Orange = 7:5:8

6. 1 \frac{1}{2} = \frac{6}{4} since \frac{1}{4} = 4 feet. Then 6*4=24 So the answer is C

7. 1200 m/8 cm = C. 1 cm = 150 m 

8. A. Since 1 in = 3 feet then 6 inches = 18 feet (6*3=18) and 4 inches = 12 feet (4*3=12) so the dimensions of her room are 16'x12'.

B. A=lxw so 16*12= 216 m^{2}

Hope that helps
