If A piece of timber has been cut in to two lengths in ratio of 7 to 2 original piece was 828cm how long is the larger piece?

Answer 1

To find the length of the larger piece, we first need to determine the total number of parts in the ratio, which is 7 + 2 = 9 parts. Next, we divide the total length of the original piece by the total number of parts to find the length of one part: 828 cm / 9 = 92 cm. Finally, we multiply the length of the larger piece's parts in the ratio by 7 (since the larger piece has 7 parts): 92 cm * 7 = 644 cm. Therefore, the larger piece is 644 cm long.

Answer 2

7/9 +2/9 = 828cm.

828/9 = 92cm.

The larger piece = 7 x 92cm = 644cm.

And the other piece = 2 x 92cm = 184cm.
