The problem asks us to express 70 cm as a fraction of 1 m, and simplify the fraction to its lowest terms.

1. Problem Description

The problem asks us to express 70 cm as a fraction of 1 m, and simplify the fraction to its lowest terms.

2. Solution Steps

First, we need to convert both quantities to the same unit. Since 1 m = 100 cm, we will express both in cm. So we have 70 cm and 100 cm.

The fraction is then $\frac{70 \text{ cm}}{100 \text{ cm}} = \frac{70}{100}$.

Now, we simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 70 and 100 is

1

0. Dividing both by 10, we get $\frac{70 \div 10}{100 \div 10} = \frac{7}{10}$.

3. Final Answer

The fraction of 1 m that is 70 cm, in its simplest form, is $\frac{7}{10}$.
