Proportionality Calculations

Use PROP ( [ MODE ] 6 ( PROP ) ) mode for proportionality
calculation.
The PROP mode lets you determine the value of X in the
proportionality expression a:b=X:d (or a:b=c:X) when the value of a,
b, c and d are known. (See Example 54)

To solve the value of X

1. Press [ MODE ] [6] [1] or [ MODE ] [6] [2].
2. Enter the value for each of required value (a, b, c, d) and press
[ = ]. To clear all the coefficients, press [ AC ].
3. When all coefficients have been entered, press [ = ] to solve the
X.
4. Pressing [ = ] or [AC] will return to the coefficient entry display.
(Note) : 1. After inputting data, press [ = ]. The registers the value
and displays up to six of its digits in the currently
selected cell.
2. you cannot transform values to engineering notation
while an equation solution is displayed.
3. A Math ERROR will occur if you perform a calculation
while 0 is input for a coefficient.
