Answer:
A!
Step-by-step explanation:
I think it’s B
Because when you get rid off^ the answer becomes +- and there is no square root for 6
Answer:
B
Step-by-step explanation:
Two friends + Bud = 3 people
7/10 = 70%, or less than a full cake
D is more than a full cake so this cannot be the answer.
C is 3/4 which 75% for <em>each</em> person, but there is only 70% to begin with so this is impossible.
B is 1/4 for each person also known as 25% for each person. 25% × 3 people = 75% which is slightly over how much cake Bud has (70%).
A is 1/2 for each person, but there isn't enough cake to go around to give each person a half piece.
The soundest solution would be B. Since the problem calls for estimations, B gives about 25% to each person, totaling to 75% after 3 people. Although we only have 70%, we are only estimating. A 5% difference is a good estimate.
So if we do not know what 12 times 9 is then we can round 9 to 10 and get
12 times 10
most people can multiply by ten so this should be easy so
12 times 10=120
12 times 9=108
she was off by 12 so a 10% deviation error
another way to do it is you multiply 12 by 10 and get 10 12's
then you subtract 1 12 and get 9 12's
