Answer:
1. 1/4
2. 13/20
Step-by-step explanation:
Find the LCD (Least common denominator)
the LCD of 8 and 16 is :
8= 8, 16, 24
16= 16, 32, 48
therefore the LCD is 16, then you divide it
16÷8= 2
16÷16= 1
Then multiply the quotient and the numerator
1x2= 2
2x1= 2
then, add the two numerators
2+2=4
the answer will be:
4/16 but if you can still simplify it simplify it
Find the GCF (Greatest common factor)
4= 1,2,4
16= 1,2,4,8,16
the GCF is 4
4÷4=1
16÷4=4
therefore the answer is
1/4
You can apply it to number 2
