Step 1: Multiply
− 32 × 24 = − 768
Step 2: Divide
−768 ÷ (−9) = 85.333....
256 = 85.33
3
So far:
256 −(−12) + (−15)
3
Step 3: Simplify signs
256 + 12 − 15
3
256 − 3
3
Step 4: Convert 3 to a fraction:
3 = 9
3
256 − 9 = 247
3 3 3
NB - 3 becomes 9
3
This is because
To convert a whole number into a fraction in this case 3 it would be denoted as;
3/1
But in this case, we are adding or subtracting fractions, so we need to write 3 with a denominator that matches the other fraction in the expression.
Therefore the Numerator and denominator are both multiplied by 3
Final Answer:
247 = 82.3
