Step-by-step explanation:
Step 1: Find the total fraction of raisins he gave to his brothers
=
Step 2: Find the lowest common multiple(Lcm) of 6 and 4
Lcm of 6 and 4 = 12
Step 3: Add the fractions
= 
= 
Step 4: To find the fraction that he kept, you will subtract the total fractions he gave his brothers from 1.

Final answer
The fraction that he kept = 
The number is -240 because -240 divided by 4 is -60
The product would be 432x^2y^3.
Length - 14 meters
Width - 7 meters
The length is twice the width - 7 times 2 = 14
There are four sides, two 14m and two 7m. 14 x 2 + 7 x 2 = 42
