It's easier then you'd expect it to be. There's no need to convert the fractions so that they all have a common denominator like you'd have to do when adding or subtracting fractions.
Let's take a look at something really simple.

We can multiply the numerators together so 1*2. We can multiply 4*6 to get the denominator.
This means that our fraction becomes
.
Now I'm assuming since you already know how to add fractions you'll know how to simply fractions. So 2/24 will become 1/12.

Answer:
7/20 of one shelf in an hour
Step-by-step explanation:
if you think about the problem in numbers out of 100, we know that
- 2/3 of an hour is 40 minutes per hour because 60/3 = 20
- 1/4 of a shelf is 25% of the shelf
In an hour Leland can build 35% of a shelf in an hour or 7/20 of a shelf
Answer:
<u>1.75 x 10^3</u>
Step-by-step explanation:
This is quite a simple question really, we just have to remember one thing, the exponent laws. When both exponents have the same base and are getting divided by each other, you subtract the exponents.
So in this case we have 10^8 on top divided by the 10^5 on the bottom, so now you just subtract the 5 from 8 and you get 3 as your final exponent. So your power would just be 10^3.
The final step is just dividing 7 by 4 which is 1.75
Combine the power and 1.75 together to get the correct notation
<u>1.75 x 10^3 </u>
The values of y are 7, 8.5, 10.5 and 11
<h3>How to determine the values of y?</h3>
The equation is given as:
y = 1/2x + 5
The domain is given as:
Domain = 4, 7, 11, 12
This means that
x = 4, 7, 11, 12
Substitute x = 4, 7, 11, 12 in the equation y = 1/2x + 5
So, we have:
y = 1/2 * 4 + 5 = 7
y = 1/2 * 7 + 5 = 8.5
y = 1/2 * 11 + 5 = 10.5
y = 1/2 * 12 + 5 = 11
Hence, the values of y are 7, 8.5, 10.5 and 11
