divided in the ratio 1:4. Find the length
of each part.
whole solution ​

Answer 1

Answer:

8.4cm

or we can say 8cm 4mm

Step-by-step explanation:

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

Answer 2

Answer:

Step-by-step explanation:

length =10 cm 5mm=105 mm

now 4x+1x=105

5x=105

or x= 105/5

so x= 21

length of each part, 1x=1.21=21 cm

another part 4.x= 21.4= 84 cm
