Arliss has two pieces of carpet runner. One is yards long and the other is yards long. She needs 10 yards of carpet runner altogether. How much more does she need to buy?

Answers

Given:
10 yards required
5 2/3 yards on hand.

We need to subtract the yards on hand from the total yards required.

First, we need to convert the mixed fraction into an improper fraction.

5 2/3 = ((5*3)+2)/3 = (15+2)/3 = 17/3

Second, we need to multiply 10 by a fraction that will give us the denominator of 3.

10 * 3/3 = (10*3)/3 = 30/3

Third, we do subtraction using our derived fractions.

30/3 - 17/3 = (30-17)/3 = 13/3

Lastly, we simplify the improper fraction. Improper fraction is a fraction whose numerator is greater than its denominator. Its simplified form is a mixed fraction.

13/3 = 4 1/3

Arliss needs to buy 4 1/3 yards more to complete the required yard length. 

Answer: 41/3

How many grandparents have my grandparents?who can solve it is very good on maths! it is just a lpgic problem! i know the answer :)

Answer: Well, each grandparent would only have two parents, and those parents would each have two parents, unless adoption was involved, so there would be four grandparents for each grandparent. Eight would be your answer, I think.
this doesn't have enough information. it spend on ages, how many children per generation, if direct bloodlines only or adoption count, half relatives, etc.

Which of the following numbers would you multiply -3/4 by to equal 1?
@Sbcardinals

Answers

Just multiply -3/4 by -4/3 :)

You have to multiply -3/4 by a negative number to make it positive and the 3/4 cancels out into 1 when multiplied by 4/3. Hope this helped!
