Is it 0.625
Yes it is, note 1.6 is one tenth of 16 and 16 is 2^4:
1/2 = 0.5
1/4 = 0.25
1/8 = 0.125
1/16 = 0.0625
just halving the numbers each iteration.
So 1/0.0625 is 16 therefore 1/0.625 is 1/1.6 from your knowledge of place value.
Of course the easy way is to shove it into a calculator.
1.6 = 16/10 = 8/5
reciprocal = 5/8 ///// as a fraction
or = 5.00000000…. / 8 = 0.625 in decimal form
Yes, reciprocal of 1.6 = 1/1.6 = 0.625
1 / 1.6 = 0.625 = 5/8
or 8/5= 1.6
8/5 —-> reciprocal 5/8
Yep, it is 0.625
you can check by multiplying the two together, it should equal 1.
it is 1/1.6
the reciprocal is just it upside down
and every number is divided by 1
it is 0.625
so you are right
What Does a Multiplicative Inverse or Reciprocal Mean?
A multiplicative inverse or reciprocal for a number n, denoted by 1n or n−1 (n to the power of minus one), is a number which when multiplied by n, their product is 1. In other words, the reciprocal of any number is one divided by that number. The reciprocal of a fraction xy is yx. To find the multiplicative inverse of a real number, just divide 1 by that number. Examples:
- The reciprocal of 7 is one senventh = 1/7 = 0,142857142857…)
- The reciprocal of 0.333… is 1 divided by 0.333…, or 3.
