Perimiter=2(Length+width)
perimiter=70
70=2(L+W)
divide both sides by 2
35=L+W

L:W=4:3
4+3=7
35=L+W
35=7 units
divide both sides by 7
5=1 unit


length=4 units
4 times 5=20
width=3 units
3times 5=15

length=20in
width=15in

Length = L   width = W
4+3 = 7
3/7 * 70 = 30
4/7 * 70 = 40
30 = 2W
40 = 2LW = 15
L = 20

How to add fractions? with unlike denominators
stellarik [79]

Answer:

The recipe calls for 19/12 or 1 7/9 cups.


Step-by-step:

In order to get this answer, we have to add all three fractions together. First, we have to find the LCM (Least Common Multiple) between the three denominators:

2: 2, 4, 6, 8, 10, 12

3: 3,6,9,12

4: 4,8,12

The LCM between these three denominators is 12.

4x3=12

2x6=12

3x4=12

You now multiply the numerator by the same number you multiplied by for the denominator in order to get 12:

3/4 becomes 9/12

1/2 becomes 6/12

1/3 becomes 4/12

We now add all the fractions together:

9/12+6/12+4/12= 19/12

We got 19/12 but the answer is an improper fraction so we turn it into a mixed number:

12x1=12 (7 remaining)

This is written as 1 7/12.

Hope this helps! :)
