120 + 144 + 143 + 111 + 167 / 5 = 551.4 This answer was calculated according to the order of operations. Rule 1: First perform any calculations inside parentheses. Rule 2: Next, from left to right, do all multiplications and divisions. Rule 3: Last, from left to right, do all additions and subtractions.
To find the average, add all 5 scores together and divide the sum by 5. 120 + 144 + 143 + 111 + 167 = 685 and 685/5 = 137
The average score (or arithmetic mean of his score) is the sum of all values divided by the number of values.Sum of all values = 120 + 144 + 143 + 111 + 167 = 685 : Number of values = 5Average Score = 685 ÷ 5 = 137.
120/143 is in its simplest form.
Think about it, your trying to find the SUM. Sum is just plus the numbers together. So, what's 36 + 84 + 23? 36 + 84 = 120. 120 + 23 = 143. There's your answer: 143. Was that so hard?
143 + 72 = 215
143 + 68 = 211
71.5 + 71.5 = 143
120% increase.
Around 160 I think
142 plus 1 makes 143
30 can go into 143 4 times because 30x4=120
9 + 120 + 300 = 429
