The number of pictures which Karli and her friend can paint in a full hour is equal to 4 pictures.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
It is given that Karli and her friend can paint 6/7 of a picture in 3/14 of an hour.
Let's assume they can paint x number of pictures in a full hour.
So , the fraction by dividing 6/7 by 3/14 can be written equal to x .
i.e.,
= x
We need to do the cross product here :
× x =
or
x = () ÷ (
)
We know that when dividing two fractions we need to change the division sign to multiplication sign by inverse the fraction value right to the division sign i.e.,
x = () × (
)
x = 84 / 21
x = 4
Therefore , the number of pictures which Karli and her friend can paint in a full hour is equal to 4 pictures.

Answer:
4 pictures
Step-by-step explanation:
(6/7)/(3/14)=x/1
cross product
3/14*x=6/7*1
3/14x=6/7
x=(6/7)/(3/14)
x=(6/7)(14/3)
x=(6/1)(2/3)
x=12/3
x=4

to understand this user the distributive property in reverse like this
ab+ac=a(b+c) so we have
-10p+9p=(-10+9)p
we add the terms in the parenthsees
-10+9=9-10=-1
so we have
-1p=12
multiply both sides by -1
p=-12
⇒ (-10+9)*p= 12 (distributive property)
⇒ -1*p= 12
⇒ -p= 12
⇒ p= -12
Final answer: p=-12~
before Sarah, but behind
Ella. Marianne finished
before Julia, but behind
Sarah. In what order did
the girls finish the race?
Answers
Answer:
Ella ............> Maria .............> Sarah ............> Marianne .............> Julia

Maria finished before Sarah, but behind Ella
So, we can infer that:
Ella finished first, followed by Maria and then Sarah
Ella ............> Maria .............> Sarah
2- For the second given:
Marianne finished before Julia, but behind Sarah
So, we can infer that:
Sarah finished first, followed by Marianne and then Julia
Sarah ............> Marianne .............> Julia
3- Combining the above parts:
By combining what we got from parts 1 and 2, we can deduce that:
Ella finished first, followed by Maria, Sarah, Marianne and finally Julia
Ella ............> Maria .............> Sarah ............> Marianne .............> Julia
