that number.

Answer 1

To find 70% of a number, divide the given value for 45% by 45 to find the value for 1%, then multiply it by 70 to find 70% of the number.

Step-by-step explanation:

To find 70% of a number, we can start by finding the value of 1%, and then multiply it by 70. Let's first find the value of 1% of the number.

We are given that 45% of the number is 81. To find 1%, we can divide 81 by 45, which gives us 1.8.

Now, we can find 70% of the number by multiplying 1.8 by 70, which gives us 126.

Therefore, 70% of the number is 126.
