1.) A 2.5-liter bottle of cola is shared between 5 friends, how much does each person get?
2.5 liter of cola
5 friends
n = 2.5 ÷ 5
n =
Each person gets 0.5 liters of cola.
2.) Seawater contains about 1.75 g salt per 500 millimeters of water. How many grams of salt would be in one liter of seawater?
1.75g of salt/ per 500 millimeters of water
1 liter
One liter = 1 000 millimeters
n = (1 000 ÷ 500) × 1.75
n = 2 × 1.75
n =
There would be 3.5 g of salt present in 1 liter of seawater.
3.) The width of the tail of a microorganism is 0.00723 cm wide. How many millimeters is this?
0.00723 cm
cm → mm
1 cm = 10 mm
n = (0.00723/ 1) × 10
n =
0.00723 cm is equivalent to 0.0723 mm.
4.) Ten items purchased at a supermarket weigh 15 kilograms. Two of the items weigh 730 grams. What is the total weight in kilograms of the other eight items?
15 kg/ per 10 items
2 items = 730 grams
kg → g
1 kg = 1000 g
15 kg = 15 000
n = 15 000 - 730
n =
The other eight items purchased at the supermarket weighs 14 270 g.
5.) A jeepney covers 7m in one second. How many kilometers will it travel in 4 300 sec?
7 m / per second
n = (4 300 ÷ 1) × 7
n = 30 100 m
m → km
1 000 m = 1 km
n = 30 100 ÷ 1 000
n =
The jeepney would travel 30.1 km in 4 300 seconds.
6.) Lois wants to send a box of oranges to a friend by mail. The box of oranges cannot exceed a mass of 10 kg. If each orange has a mass of 200g, what is the maximum number she can send?
10 kg
200 g
kg → g
1 kg = 1 000 g
10 kg = 10 000 g
n = 10 000 ÷ 200
n =
Lois could send a maximum of 50 oranges to her friend via mail.
