Answer 1

Converting into same units.
∵ 1m = 100 cm 
∴ 1m 5cm = 100 cm + 5 cm = 105 cm
∴ 1m 5cm : 63 cm = 105 cm : 63 cm = 7 × 5 × 3 : 7 × 3 × 3 = 5 : 3

Answer 2

Answer:

The simplest form of given expression is 5:3.

Step-by-step explanation:

We know that

1 m = 100 cm

1 m 5 cm = 100 + 5 =105 cm

The given expression can be written as

$\frac{\text{1 m 5 cm}}{63cm}=\frac{105cm}{63cm}\Rightarrow \frac{105}{63}=\frac{5}{3}$

Therefore the simplest form of given expression is 5:3.
