you can multiply 20 by 2.53 by taking apart two. 53 and multiplying each part by 20 and then adding the products which equation shows this method.
The equation that shows this method is:
20 × 2.53 = (20 × 2) + (20 × 0.53)
The equation that shows this method is:
20 * (2 + 0.53) = (20 * 2) + (20 * 0.53)
The method you mentioned, where you break down 2.53 as 2 + 0.53 and then multiply each part by 20, can be represented using the distributive property of multiplication. Here's how you can write this method as an equation:
20 * 2.53 = 20 * (2 + 0.53)
By applying the distributive property, the equation becomes:
20 * 2.53 = (20 * 2) + (20 * 0.53)
This simplifies to:
20 * 2.53 = 40 + 10.6
Which further simplifies to:
20 * 2.53 = 50.6
So, the equation that shows the method you mentioned is:
20 * 2.53 = (20 * 2) + (20 * 0.53)
