Answer:
A. 25-12.3 B. -25-12.3 C. -25+12.3
Step-by-step explanation:
Because when a number has a coefficient we multiply the base number by that coefficient in this case 50 1/2 or 50/2 = 25 When a negative number is added to a number it is the same as normal subtraction but when a negative number is subtracted from a number it is reversed and is addition. Ex. 2+(-2)=0 and when reversed 0-(-2)=2
