The binary number 10101010 is equivalent, in decimal representation, to 128 + 32 + 8 + 2 = 170. But this answer assumes that the given number is binary - an assumption for which there is no real justification. Besides, the relationship is an equivalence, which is not quite "the same thing".

We don't know what the base of the given number is. Since the only digits shown are 1's, the base could be anything from 2 and up. Whatever the base is, the given number is (base + 1). If " 0 0 0 0 1 1 " is a binary number (base 2), then the decimal equivalent is 3 .

Take the number and divide it by 100.

As per the 8421 rule the given binary number can be solved as : 0 0 0 0 0 1 1 1 0 0 0 0 0 4 2 1 i.e : 4+2+1 = 7 So the answer is 07 in decimal for 00000111 in binary

I assume that you are asking how to convert the binary: 011110 to decimal. First off there are 6 places in this binary number--actually five, being that the last number is 0 (a place-holder). So, charting or making a table: Binary CalculationDecimal EquivalentOriginal Binary NumberAdd together2010021212224142381824161162532002664Not givenNot given Add together the last column of numbers together will give you the decimal equivalent to the binary number: 011110.

Yes, it can but it all depends on what the given decimal is!

An equivalent decimal is a decimal that is equal.Example:5.09 is equal to 5.090.

0.90

Percent means to divide by 100. so if given 25%, the decimal equivalent is 25/100 which is 0.25. Likewise if given 12.4%, the decimal equivalent is 0.124. (Notice how the decimal moves two places to the left.)

You turn the decimal into a fraction. Then you can find the equivalent fraction.

Multiply that number by the decimal equivalent of the percentage. 70% of 340 = 340 x 0.7 = 238
