Answer:
13
Step-by-step explanation:
to round to nearest whole number if its .5 or above you go up 1. If it's .4 or below you go down 1.
2.414=2
8.160=8
2.621=3
add
2+8+3=13
if you just added the decimals you would get: 13.195. (This shows you have a good estimate.)
The average weight is 114 pounds of all 5 children.
3 * 120 = 360
2 * 105 = 210
210 + 360 = 570
570 / 5 = 114
Let x be the number we are searching for.
(3/4)x = 1/10
