Answer:
<h2>D</h2>
The cube of twice a number decreased by 11
Answer:
10:1:5
Step-by-step explanation:
Given that,
A game was played by Amy, Bill, and Cara.
Let Amy's score be x. Then,
Bill's score would be x/10
Cara's score = x/2
Now,
The ratio of their scores;
x: x/10: x/2
= 1 : 1/10 : 1/2
To equalize the scores, multiply all of them by 10
= (1 * 10): (1/10 * 10) : (1/2 * 10)
= 10 : 1 : 5
Thus, the simplest ratio form would be 10:1:5
Answer:
50/50
Step-by-step explanation:
Answer:
1.
-9 11/15
2. 11/24
3.
34/45
4. -5.05
5. -0.622
Step-by-step explanation:
1. -2 4/5 - 6 2/15
convert them to a common denominator and an improper fraction:
-2 4/5= 18/5=- 54/15 -6 2/15= 92/ 15
*15 is the other denominator, so you keep the numbers in the second number the same*
subtract: -54/15- 92/15
since you are subtracting a negative number it goes farther away from zero
-146/15 or -9 11/15
2. -5/12 + 7/8
convert them to a common denominator
-5/12=- 20/48 7/8= 35/40
add: -20/48+35/40
11/24
since you are adding a negative number it goes closer to zero or past zero:
3. 3 3/5 x 2/9
convert 3 3/5 to an improper fraction: 18/5
mulitply the two denominators and the two numerators
17/5 x 2/9= 34/45
This is also the simplest form.
4. Convert to a decimal. -5 1/20
keep the -5 beacuse that is a whole number
divide 1/20 to turn it to a decimal to get 0.05
5. Which number is the largest? -0.65, -0.622, -5/8
to find this you would have to convert all numbers to either a decimal or a fraction.
5/8 is 0.625
the one closest to zero is the largest which is -0.622
