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

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

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

$Cranberry:Apple:Orange = 7:5:8$

PLS HELP ME 6, 7, and 8 (SHOW WORK!!) + LOTS OF POINTS + THANKS! + BRAINLIEST IF POSSIBLE!

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
