Question

draw a line segment of length 7.4 cm and divide it in the ratio 5: 8

Answer 1

let length=5x and 8x
5x+8x=7.4
13x=7.4
x=0.56 cm
1st length=5x=5(0.56)=2.8 cm
2nd length=8x=8(0.56)=4.48 cm

Answer 2

let length= 5x and 8x

5x+8x=7.4

13x=7.4

x = $\huge\frac{7.4}{13}$

x = $\huge\frac{74}{130}$

x=0.56 cm

first length=5x=5(0.56)=2.8 cm

second length=8x=8(0.56)=4.48 cm
