Draw a line segement of lenght 6.3cm and divied it interlly in the ratio 3:4​

Answer»

Answer:

Let the line segment be PR and Q be a point on that line segment.

PQ:QR = 3:4

Let PQ & QR be 3x and 4X respectively

Total lengths of line segment = 6.3 cm

PQ + QR = 6.3 cm

3x + 4x = 6.3 cm

7x = \frac{63}{10} cm \\ x = \frac{63}{10} cm \times \frac{1}{7} \\ x = \frac{9}{10} cm \\ x = 0.9 \: cm

Hence,

PQ = 3x = 3 × 0.9 cm = 2.7 cm

QR = 4x = 4 × 0.9 cm = 3.6 cm
