Question

a Ribbon 10 cm 5 mm long is to be divided in the ratio 1 ratio 4 find the length of each part ​

Answer 1

Step-by-step explanation:

let l =x then another length =10.5-x

then solve it

Answer 2

Length of the ribbon

= 10cm 5mm

= 100mm +5mm

= 105 mm

Ratio = 1:4

let common ratio be x, then;

1x+4x = 105

5x = 105

X = 21

Hence the length of each part will be;

1x = 1×21 = 21mm = 2cm 1mm

4x = 4×21 = 84mm = 8cm 4mm
