Two decimals that are equivalent to 3.200
AleksAgata [21]

Answer:

Two or more decimal numbers are said to be equivalent decimals, when they name the same value (or same amount). For example, the decimals: 0.2 = 0.20 = 0.200 = 0.2000 etc. Thus by successive addition of zeros after the decimal part of the number after the decimal point means the same number and hence are equivalent. Therefore, the decimals: 5.3, 5.30, 5.300, 5.3000 etc are all equivalent.

natima [27]

Answer:

3/4,

12/16,

18/24,

24/32

30/40

...So on, So on...

Step-by-step explanation:

Any fraction that you multiply by the same number on the bottom and on top.

So, multiply by two, what you do to the top do to the bottom. = 12/16

Multiply by three = 18/24

So on, so on.

Or you can reduce, 6/8 divide by 2 = 3/4.

I'm gonna give you 5 equivalent equations. I also taught you how to do it!
