Answer:
1.) subtract = 1 1/3 - 3 1/2 = answer
2.) subtract = 6 3/4 - 1 1/2 = answer
3.) add = 3 1/4 + 2 1/8= answer
4.) subtract = 4 3/4 - 2 1/6 = answer
Step-by-step explanation:
5.) 3 lawns = 6 3/4 hrs
1st lawn 2 1/2 hrs
2nd lawn 1 3/4 hrs
add 2 1/2 + 1 3/4 = total
then 6 3/4 hrs - total = the amount it takes to mow the 3rd lawn
im sure u know how to add and subtract fractions is u r in middle school :)
The club can buy 5 computers with $3472
Step-by-step explanation:
The number of computers which can be bought from the given amount will be calculated by dividing the amount by price of one computer.
Given
Total amount = $3472
Price of one computer =$680
The number of computers will be:

As the number of an item cannot be in decimal it will be rounded off to 5.

2a because with 18a and 20ab they both have "a" in common and they are even thus multiples of 2 leaving you with 2a(9,10b)
Rational exponents

work like this: the numerator is the actual exponent of the base, while the denominator is the index of the root.
In other words, we have
![a^\frac{m}{n}=\sqrt[n]{a^m}](https://tex.z-dn.net/?f=a%5E%5Cfrac%7Bm%7D%7Bn%7D%3D%5Csqrt%5Bn%5D%7Ba%5Em%7D)
So, in you case, we have
![\sqrt[5]{x^3}=x^\frac{3}{5}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%5E3%7D%3Dx%5E%5Cfrac%7B3%7D%7B5%7D)
Assuming that the question contanis a typo. If you actually mean
,
then you can write it as 
In order to determine the probability that the coin chosen is a dime, determine first the total number of sample coins. In this problem, there are 52 coins all in all. Next, divide the number of dimes in the sample with the total number of coins. This gives us 10/52. Simplifying the fraction further yields to 5/26. Thus, the probability that the coin chosen is dime is 5/26. The answer is letter c.
