Answer:
20/9
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 80 and 36 is 4
Divide both the numerator and denominator by the GCD
80 ÷ 4
36 ÷ 4
Reduced fraction: 20/9
Answer:
I would rather use their multiples.
Step-by-step explanation:
With 13 and 14, neither number has many factors (and few prime factors, for that matter) so factoring would be pretty much useless. If you wanted to use the prime factors of 14 (7 and 2) multiplying either of them by 13 would not give you the LCM. Actually the LCM is just 13*14 which is 182.
Good luck!
Answer:
22
Step-by-step explanation:
if a=15
then, 2(a-5)+2= 2(15-5)+2 = 2(10)+2= 20+2=22
