Step-by-step explanation:

LCD: Least Common Denominator.

Always remember that term when simplifying, multiplying, addidng, and dividing fractions with different denominators.

Numerator: Boring ter for top number

Denominator: Fancy term for bottom feeder. . . I mean, <em>number.</em>

<em />

7/10 + 2/5

To begin, you need to find how to make 2/5 equal ?/10. Why 10 as the denominator, you ask? Because LCD rule states you must find LOWEST COMMON MULTIPLE of the two denominators, which, in this case, happens to be 10! Lucky you.

SO, 7/10 + ?/10. . . now, how do you find the numerator (?)

Well, rules of math ALWAYS state what you do to ONE side must be replicated to the OTHER side, In this case, you changed 2/5 to ?/10, meaning you multiplied the 5 by TWO to get 10. This means you must multiply the 2 by TWO to answer the numerator!!

so, 2/5 now becomes 4/10.

Add!

7/10 + 4/10 = 11/10. This is known as an improper fraction. These guys have absolutely no manners or common decency to the math world. Make them PROPER by backslapping them into their place! Rather, into their <em>whole & proper </em>place, I should say.

11/10 is an improper fraction and can be transferred into 1 & 1/10

(When writing it, make the 1 REALLY big and the 1/10 REALLY small. This is because the 1 is a superior WHOLE number and the 1/10 is a measly fraction still. Respect.)

Hope this helps!

Answer:

11/10 or 1 1/10 or 1.1

Step-by-step explanation:

7/10+2/5

7/10+4/10 you want to make the denominator the same

11/10         now that the denominators are the same you can add the              numerators

I'm sorry but maybe you wrote this wrong. If Wendy has 1 pint of milk and only needs 1 pint of milk, then she has exactly the amount she needs.

A group of 6p people are renting a vacation house together the price of the rental is 3p to the 2nd power if they split the cost
Tanya [424]
So we just do
cost/number of people=cost per 1 person
so
(6p)/(3p^2)
remember that you can split it up and make ones
\frac{6p}{3p^{2}}=\frac{6}{3p} times \frac{p}{p}=\frac{2}{1p} times \frac{p}{p} times \frac{3}{3}=\frac{2}{1p}  times 1 times 1=2/p

easy way is
remember that
(x^m)/(x^n)=x^(m-n)
so
(6p)(3p^2)=6/(3p=2/p=2p^-1


each member pays 2/p
