The quotient is easy. Since the calculator drops any fractional portion when in base mode, simply do the division. For example, to get the quotient of 5 and 3, divide 5 by 3 and see 1.
The remainder is a bit harder. Subtract the product of the quotient and the divisor from the dividend. For example, to get the remainder of 5 and 3, first calculate the quotient as above. Then subtract 1*3 from 5 and see 2.

How to change a decimal value to binary number in fx-85GT PLUS ? Thanks!!

Let's do the preocess so it will work on any calculator.

As an example, convert 68 from decimal to binary.

The decimal columns are 10^0, 10^1, 10^2, 10^3, etc.

The binary columns are 2^0, 2^1, 2^2, 2^3, etc.

Flipping to the normal left to right, we get 2^6, 2^5, 2^4, 2^3, 2^2, 2^1, 2^0.

64 32 16 8 4 2 1

We divide our number, 68, by 64, and get 1 with a remainder of 4. We next divide our remainder by 32, 16, 8, and finally 4, where we get 1 with no reminder.

In binary, this works out to 1000100. To check, we multiply the ones by the respective column values and get 64 + 4 = 68.

Good luck.

How come i dont get the right answer for example 120 divided by tan68 = -58 instead of 45?

Make sure your calculator is set to the desired angular mode.

The quotient of 120 divided by the tangent of 68 radians is about -58.82, as your calculator is giving you.
The quotient of 120 divided by the tangent of 68 degrees is about 48.48 . The quotient of 120 divided by the tangent of 68 grads is about 65.97 .

Luke wants to find the difference 175 - 134. He has subtracted the hundreds and tens so far. What is the sum of the two numbers he has subtracted? How much does he still need to subtract?

SUM means adding not subtracting. so if you were wanting to add the total (the sum) of the amounts of the hundreds and the tens would be 170 plus 130 which would be 300 but the remainder from subtracting 130 from 170 would be 40. That would leave the single units 5 minus 4 of which the remainder is 1. So, the remainder from subtracting 134 from 175 is the reminder of subtracting the one hundred from the one hundred which is zero added to the remainder of subtracting the tens (70 minus 30) which is the remainder of 40 plus the remainder of subtracting the units of 5 minus 4 which is 1. So you need to add the 0 and the 40 and 1 which is the remaining sum of 41.

Write a program that accepts two numbers a and b and divides a by b and displays the quotient and the remainder..


a = 0
b = 0
c = 0
input "First number "; a
input "Second number "; b
c = int ( a / b )
d = ( a / b ) - c
print "Quotient: "; c
print "Remainder: "; d

What is base 6 of 486

for converting 486 to the base 10 to base 6 dived 486 by 6 and note the quotients and remainder.

486/6 = quotient = 81 remainder = divide quotient by 6 and note quotient and remainder.

81/6 = quotient 13 remainder= 3

13/6 = quotient 2 remainder = 1 .

2/6 = quotient 0 remainder= 2.

Hence reading remainder from below we get 2130.

So 486 tot he base 10 is equivalent to 2130 to the base 6.

Thank you.

How do you convert decimals into fractions on the calculator

Building supply houses (Home Depot) have builder's calculators that can do it.
The other method is tedious, by multiplying the remainder by the desired quotient, until you have near whole numbers.
