2.
of each part WITH WHOLE SOLUTION PLS​

Answer 1

Step-by-step explanation:

Length of ribbon = 10cm 5 mm = 105mm

Sum of ratio terms = 1+4= 5

therefore length of 1st part = 1/5 × 105 = 21mm = 2cm 1 mm

length of 2nd pert = 4/5 × 105 = 84 mm = 8 cm 4 mm

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
