please make me the brainliest

Answer 2

Answer: length of each piece are 35 cm and 10 cm respectively.

Step-by-step explanation:

Since the ratio is 7:2, you can start by thinking of it as 9 pieces. If you divided the board into 9 equal pieces, they'd each 5 inches long, because 45 divided by 9 = 5.

But since they're in the 7:2 ratio, you have (7 x 5) to (2 x 5), or 35:10

So one is 35 cm, the other is 10 cm

In simpler words, it's 7x + 2x = 45. (So 9x = 45, and x = 5. So 7x = 35, and 2x = 10.)

Hope this makes sense!

Thanks!
