I'll do the first two to get you started.

# 3

Percent Right = (Number he got right/total questions) * 100 =

So he got 88.89% of the test questions right

------------------------------------------------

# 23

Note: 1 kilogram = 2.205 pounds (approximately)

So if you multiply 45 pounds by the fraction you get

So 45 pounds is approximately 20.408 kilograms

So the answer rounded to the nearest tenth is 20.4 kilograms

3.)subtract 6 from 54 to get the # right then divide by 54 to get the percentage right. # of right/# possible=48/54=24/27=8/9=.888 or % correct
23)....the 1kg=2.205 pounds....so we must divide 45 by 2.205 and that will give us the weight in kilo grams. kg
:
45) x +.023(x)=10.55
.....1.023x=10.55
..... amount of avg wage last year
10) 1 liter =33.81 ounces so 2 liters = 67.62.......now we divide this by the 5 ounce servings for each child.
67.62/5=13.52 servings but we know that only children will get a full 5 ounce serving. 52/100 of an ounce is left over.
