Answer:
A. GCF(a,b) = 
B. LCM(a,b) = 
Step-by-step explanation:
The GCF of two or more integers is their greatest common factor. In order to find it, you must factorise them first and then do the product of the factors that appear in all the factorisations, with their least exponent.
Hence, the GCF of 
and 
is .
The LCM of two or more integers is their least common multiple. In order to find it, you must factorise them first and then do the product of the multiples that appear in one or all the factorisations, with their greatest exponent.
Hence, the LCM of and is
First find out how much money she spent by doing 80 (original amount) - 33.56 (amount after spending): $46.44
Now she spent 46.44 dollars and each pound is 7.74:
46.44 / 7.74 = 6
She bought 6 lbs
Answer:
900m
Step-by-step explanation:
So your base is -400m so what you want to do is add up till you get to 0. So you add 400m to get to zero. Then you need to subtract from 500m until you get to 0. So you have 500m. Then you add 400m and 500m (400m+500m) which gives you the answer 900m.
Answer:
75%
Step-by-step explanation:
The percent increase is calculated as
percent increase = 
× 100%
increase = 7 - 4 = 3, thus
% increase = 
× 100% = 
= 75%
