Answer: The answer in decimal form is 0.75
Step-by-step explanation: We know Ramon has 7/8 cup of cottage cheese.
He wants to know how many 1/4 cup servings can he make. 1/4 can also be written as 2/8 cup servings. 1/4 and 2/8 are equivalent.
He can only make three 1/4 cup servings of cottage cheese.
3 x 1/4 = 3/4
3/4 written in decimal form is 0.75
60x10=600. So you have to get 40 to 400 so 40x10=400. So the answer is A.
Tenth:44.600
What is in the tenths place? The 5.
What is to the right of it?
The 8
Since the 8 is bigger than 5 you have to round up
Hundredth: 44.590
What is in the hundredth place?
The 8
What is to the right?
A 6
Since 6 is bigger than 5 you have to round up
Whole: 45
This us the same thing as rounding to the ones place.
What is in the ones place?
The second 4
What is to the right?
A 5
Since the 5 is big enough, it forces the 4 to round up.

Let Billy have x common cards, and y premium cards:
(i) Billi has 124 cards:
x+y=124
(ii) the total value of the cards is 81.50$:
0.5x $ + 1.00*y $= 81.50 $, so
0.5x+y=81.5
we can write y=81.5-0.5x and substitute in (i):
x+y=124
x+(81.5-0.5x )=124
x+81.5-0.5x=124
x-0.5x=124-81.5
0.5x=42.5
x=42.5/0.5=85
y=124-85=39
Answer: Billy has 85 common cards and 39 premium cards
