Answer:

1 cm to 7.5 m

Step-by-step explanation:

A drawing scale is a ratio of two numbers.

The given scale, 4 cm to 30 m, can be written as a ratio in the form of a fraction,

(4 cm)/(30 m)

Since it can be written as a fraction, it can also be reduced like a fraction.

The problem wants the number of cm to be 1 cm. We have 4 cm.

Divide the numerator and denominator by 4.

(1 cm)/(7.5 m)

Now write it in the format the problem asks.

1 cm to 7.5 m
