Question

1320x7/2x22x10.5=20 how?​

Answer 1

Answer:

The answer for the equation 1320x7/2x22x10.5=20

Step-by-step explanation:

let us solve the given equation in steps to understand  how the value of the equation is 20.

1320x7/2x22x10.5=1320x7x10/2x22x105 (writing 10.5 as a fraction)

dividing 1320 and 22 by 11, we get 120x7x10/2x2x105

dividing 120 by 4(2x2 in denominator) and dividing 105 in denominator by 7 in numerator we get, 30x1x10/1x1x15

dividing 30 in numerator by 15 in denominator we get 2x1x10/1x1x1

The final answer is 2x10=20

Therefore the given equation evaluates to 20.

Answer 2

Given: 1320x7/2x22x10.5=20

To find Prove the above expression

Solution: In arithmetic mathematics, an operation that is used to determine the product of two or more numbers, this operation is known as multiplication. The result obtained in solving multiplication is termed a product.

In arithmetic mathematics, an operation that is used to divide two numbers, this operation is known as division. The terms associated with the division are dividend, quotient, remainder, and divisor.
