Question

Express in meters using decimals.
9 m and 7 cm

Answer 1

Hint: Here in this question, we have to express the given length in only unit i.e., meter using a decimals, this question belongs to conversion topic that is we have to convert the unit from one form to other here we have to convert the unit cm to the unit meter first we have to find the 1 meter is how many centimeters by using the given hint in the question and next by using a decimal simplification we get the required solution.

Complete step-by-step answer:
The meter (m) and centimeter (cm) are the units to measure the length quantities.
 Length is the measurement of the distance between two points, two things or two places. To measure length, a unit of measurement is used. There are two different systems for measuring: customary and metric. This concept is about Customary Units of measurement.
The most common customary units of measurement are the meter and centimeter.
Consider the given data in question:
9 meter and 7 centimeter i.e.,
As we know,
1m = 1 meter
1 cm = 1 centimeter
But
1 meter = 100 centimeter
\[ \Rightarrow 1m = 100cm\]
Given,
\[ \Rightarrow 9m\] and \[7cm\]
\[ \Rightarrow 9\left( {100} \right) + 7\]
\[ \Rightarrow 900 + 7\]
\[ \Rightarrow 907cm\]
Let
100 centimeter = 1 m
907 centimeter = x meter
On cross multiplication, we have
\[ \Rightarrow x = \dfrac{{907}}{{100}}\]
\[ \Rightarrow x = 9.07m\]
Hence, 9 m and 7 cm is equal to 9.07 m.
So, the correct answer is “ 9.07 m”.

Note: We have different units for solid quantity, liquid quantity and gaseous quantity. Every quantity has a measurement unit from the low quantity to the high quantity. While converting the unit of a quantity from one form to another form we have standard value. By multiplying or dividing we can convert the unit of the quantity. We have a different system of measurement of a quantity.
