A 274cm timber is cut into three pieces in the ratio 3:7:11,find the length of each ratio.

To find the length of each ratio, we first need to find the total number of parts that the ratio is divided into. In this case, the ratio is divided into parts of 3 + 7 + 11 = 21 parts.

Next, we can find the length of each part by dividing the total length of the timber, which is 274 cm, by the total number of parts.

Length of each part = Total length of timber / Total number of parts

Length of each part = 274 cm / 21 parts

Length of each part ≈ 13.05 cm

Now, we can find the length of each piece by multiplying the length of each part by the corresponding ratio number.

Length of first piece = Length of each part * Ratio number for the first piece
Length of first piece = 13.05 cm * 3
Length of first piece ≈ 39.16 cm

Length of second piece = Length of each part * Ratio number for the second piece
Length of second piece = 13.05 cm * 7
Length of second piece ≈ 91.35 cm

Length of third piece = Length of each part * Ratio number for the third piece
Length of third piece = 13.05 cm * 11
Length of third piece ≈ 143.55 cm

Therefore, the lengths of each piece are approximately:
- First piece: 39.16 cm
- Second piece: 91.35 cm
- Third piece: 143.55 cm

To find the length of each piece, we need to determine the value of each part of the ratio.

Let's set up the equation to solve for the ratio's values:

3x + 7x + 11x = 274

Adding the terms on the left side, we can simplify the equation:

21x = 274

Now we can solve for 'x':

x = 274 / 21
x ≈ 13.05

Next, we can substitute the value of 'x' back into the ratio to find the length of each part:

3x = 3 * 13.05
≈ 39.15 cm

7x = 7 * 13.05
≈ 91.35 cm

11x = 11 * 13.05
≈ 143.55 cm

Therefore, the lengths of the three pieces are approximately 39.15 cm, 91.35 cm, and 143.55 cm, respectively.

Divide 274 by (3+7+11) = 13.05

3 * 13.05 = ?

7 * 13.05 = ?

11 * 13.05 = ?
