Ratio of 7m to 9m
$))$
​

Answer 1

answer = 100:3

Here, we are given numbers as 9m and 27cm. For writing any two numbers we must have the same units so let us first make their units the same. For this, let us change units of 9 from meters to centimeters. We know that 1 meter is equal to 100 centimeters. Therefore, 9 meter will be equal to 9×100=900 centimeter.

Hence, we need to find the ratio of 900cm to 27cm or we can say 900 to 27.

Since number before to is written first and number after to is written next.

So our ratio looks like this: 900:27

But let us simplify it. For this, let us write it in division form we get: 90027.

As we can see, 3 divides both 900 and 27 so dividing the numerator and denominator by 3 we get: 900÷327÷3=3009.

Again, 3 divides both 300 and 9, so dividing the numerator and denominator by 3, we get: 300÷39÷3=1003.

Our simplified division is 1003. It can be written in ratio as 100:3.

Hence 100:3 is our required ratio.

Answer 2

Answer:

So 1 meter = 100 centimeters. 1 m by 50 cm = 100 cm by 50 cm. That equals 2 to 1 ratio.
