Diana works at a clothing store. She sold 1/5 of the total number of green shirts on Monday and 3/12 of the total number of gree
n shirts on Tuesday. What fraction of green shirts did Diana sell on Monday and Tuesday? 27/60 is the answer. Diana sold 2/15 of the total number of green shirts on Wednesday. What is the difference in the fraction of the total number of green shirts that were sold on Tuesday and Wednesday?
If the integers have the same absolute value ... they're the same number but with different signs ... then their sum is zero.
Example: (plus) 927 added to (negative) 927 = zero
If the integers have different absolute values ... they're different numbers with different signs ... then their sum has the same sign as the one with the bigger absolute value.
Examples:
==> (plus) 92 added to (negative) 91 92 and 91 are 1 number apart on the number line. The positive number is bigger than the negative number. So the sum is +1 .
==> (plus) 35 added to (negative) 37 35 and 37 are 2 numbers apart on the number line. The negative number is bigger than the positive one. So the sum is -2 .
