Question

a piece of string is 175 cm was cut into two pieces the ratio of length was 5:
2 find the length of each piece

Answer 1

Length of first piece=(5/5+2)*175=5/7*175=125cm
Length of second piece=(2/5+2)*175=2/7*175=50cm

Answer 2

Length of the 1st string = 5x cm

Length of the 2nd string = 2x cm

Total length = 175 cm

5x +2x = 175

7x = 175

x = 175/7

x = 25 cm

length of 1st string = 125 cm

length of 2nd string = 50 cm
