Chapter Review - Measurement | Cambridge Maths Milestone | Mathematics | Class 4
How many metres are there in 46 km 206 m?
a. $4206 \mathrm{~m}$
b. $46206 \mathrm{~m}$
c. $46000 \mathrm{~m}$
d. $4626 \mathrm{~m}$
The length $ 46 , \text{km} $ is equivalent to $46000 , \text{m} $. Adding $ 206 , \text{m}$ to this gives:
$$ 46000 , \text{m} + 206 , \text{m} = 46206 , \text{m} $$
Therefore, the correct answer is: b. $46206 , \text{m} $
Add $271 \mathrm{~km} 45 \mathrm{~m}$ and $49 \mathrm{~km} 870 \mathrm{~m}$.
a. $320 \mathrm{~km} 915 \mathrm{~m} \quad$
b. $329 \mathrm{~km} 15 \mathrm{~m}$
c. $302 \mathrm{~km} 915 \mathrm{~m}$
d. $320 \mathrm{~km}$

Exercise 10.2 - Measurement | Cambridge Maths Milestone | Mathematics | Class 4
Which operation is used to convert higher units to lower units?
i. Addition
ii. Multiplication
iii. Division
iv. Subtraction
To convert higher units to lower units, the operation used is multiplication. This is because to express a larger unit in terms of a smaller unit, you multiply by the factor that indicates how many smaller units are in one larger unit. For example, to convert kilometers to meters, you multiply the number of kilometers by (1000) because there are (1000) meters in a kilometer.
Therefore, the correct answer is:
ii. Multiplication
$\frac{1}{4} \mathrm{~kg}=$
i. 200
ii. 250
iii. 400
iv. 500

Here are the results for the calculations of the mixtures of measurements given in the tables:
a. Adding centimeters: $$ 34 , \text{cm} + 72 , \text{cm} = 106 , \text{cm} $$
b. Mixture of grams and milligrams: $$ 4 , \text{g} + 615 , \text{mg} - 1 , \text{g} - 210 , \text{mg} = 3.405 , \text{g} $$
c. Mixture of liters and milliliters: $$ 8 , \text{L} + 141 , \text{mL} + 7 , \text{L} + 890 , \text{mL} = 16.031 , \text{L} $$
d. Mixture of meters and centimeters: $$ 5 , \text{m} + 80 , \text{cm} - 5 , \text{m} - 37 , \text{cm} = 43 , \text{cm} $$
e. Mixture of grams and milligrams: $$ 6 , \text{g} + 227 , \text{mg} + 3 , \text{g} + 813 , \text{mg} = 10.04 , \text{g} $$
f. Mixture of kilograms and grams: $$ 16 , \text{kg} + 425 , \text{g} - 5 , \text{kg} - 889 , \text{g} = 10.536 , \text{kg} $$
g. Mixture of centimeters and millimeters: $$ 38 , \text{cm} + 4 , \text{mm} - 24 , \text{cm} - 9 , \text{mm} = 13.5 , \text{cm} $$
h. Mixture of kilometers and meters: $$ 9 , \text{km} + 764 , \text{m} - 2 , \text{km} - 569 , \text{m} = 7.195 , \text{km} $$
