To find what fraction of 1 meter is 70 centimeters, we need to express both measurements in the same units and then compare them. Since we are asked what fraction of a meter is a certain number of centimeters, it's easiest to work with centimeters.
First, we know that 1 meter is equivalent to 100 centimeters. The question is asking us to find the fraction that represents 70 centimeters as part of 1 meter.
To represent this as a fraction, we take the number of centimeters we have (70 cm) and place it over the total number of centimeters in a meter (100 cm):
\[ \text{Fraction} = \frac{70 \text{ cm}}{100 \text{ cm}} \]
To simplify the fraction to its lowest terms, we find the greatest common divisor that both the numerator (70) and the denominator (100) share. Looking at the numbers, we can see that both are divisible by 10.
Dividing both the numerator and the denominator by 10, we get:
\[ \text{Simplified Fraction} = \frac{70 \div 10}{100 \div 10} = \frac{7}{10} \]
So, 70 centimeters is \(\frac{7}{10}\) (seven-tenths) of a meter when expressed as a simplified fraction.
