68 in a fraction and simplest form and a mixed number

Fraction . . . 68/100

Fraction in simplest form . . . 17/25

Mixed number . . .
A mixed number is a whole number plus a fraction.  Since part of it is a whole
number, a mixed number is always more than ' 1 '.  But  .68  is less than ' 1 ',
so there's nothing you can do to it to make it a mixed number.  It doesn't have
what it takes.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
