Answer:
17/60
Step-by-step explanation:
First we find the LCM of 10, 12, and 5, which is 60.
He started with 54/60.
He gave away 12/60, leaving 42/60.
He gave away another 25/60, leaving 17/60.
He had 17/60 of a pizza left over.
Answer: 17/60
Change all of the fractions to have a common denominator:
LCM of 10, 12, 15 is 60
You get 12/60, 25/60, and 54/60.
54/60 is what he had at the start, and so you can just subtract what he gave away
54/60-12/60=42/60
42/60-25/60=17/60
17 is a prime number so you cannot simplify the fraction
The answer is A i must took the test
The numbers are 10 and 5
x+y=15
(1/x)+(1/y)=(3/10)
(1/(15-y))+(1/y)=(3/10)
x=10, y=5
100.5
22/7*2^2*8
=22/7*4*8
=22/7*32
=100.5
the answer is 5
B
( point E)
