Answer:
Step-by-step explanation:
<u>Cost of each item:</u>
- Pencils = 2p
- Calculators = 25c
- Rulers = 4r
<u>Total cost as expression:</u>
Factor an 8 out of both numbers: You're left with 5 and 12. The two numbers are relatively prime so we cannot factor any more out of both numbers.
Thus 8 is our greatest common factor.
When sorting fractions without expressing them as decimal values you have to keep in mind that the greater the denominator is, the smaller the value of the fraction.
For
The denominator in the first fraction is smaller than the denominator in the second one, so we know that the value of the first fraction is greater than the value of the second one.
To prove it you may express them as decimal values:
This inequation is true.
For
The denominator of the first fraction is greater than the denominator of the second one → 4>2, this means that the first fraction represents a value smaller than the second one.
This inequation is true
For
The denominator of the first equation is greater than the denominator of the second one 8>3, this means that the value the first fraction represents is less than the value of the second fraction.
This inequality is false.
For
The denominator of the first fraction is less than the denominator of the second one 2<7, this means that the first fraction is greater than the second one, so this inequation is false.
Answer:
1. I need to see the table to answer that
2. I think you need to find the probability of getting 1, H. That probability is 1/10 which is also 10%.
3. can't answer a, but b is 1/14 or 7%
4. as a fraction= 1/6
as a percent= 17% (rounded up)
Step-by-step explanation:
2. I just took the outcome needed and decided by the possible outcomes.
3. That was a compound event so I just got the probability of flipping tails (1/2) and multiplied it by the probability of getting a white ball (1/7)
4. another compound event, I got the probability of getting a medium (1/3) and multiplied it by getting yellow (1/2)
hope this helped!
Answer:
x = 1/5
Step-by-step explanation:
1/7 x = 1/35
Multiply each side by 7
7 * 1/7x = 7* 1/35
x = 7/35
x = 1/5
