Question

draw a line segment of length 7.2cm and divide it into in the ratio 5:3, measure the each part​

Answer 1

Answer:

$total \: length \: = 7.2cm$

$after \: divide \: 5: 3 \\ 5x + 3x = 7.2 \\ 8x = 7.2 \\ x = \frac{7.2}{8} \\ x = \frac{72}{80} \\ x = \frac{9}{10}$

$one \: part \: will \\ 5x = 5 \times \frac{9}{10} \\ = \frac{9}{2} = 4.5 \\ \\ second \: part \: will \\ 3x = 3 \times \frac{9}{10} = 2.7$
