We could use 7+7=14 to find the sum of 6+7.

Explanation: 
7+7=14 is one of the two closest doubles to 6+7.
We know that:
7 is 1 more than 6; this means:
7+7 will be 1 more than 6+7.
7+7=14, so finding 1 less,

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

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

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

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