Aya bought $2\dfrac{3}{10}$ kg of strawberries, and $1\dfrac{5}{100}$ kg of apples. What is the total number of kilograms she bought?
Answer:$2\dfrac{3}{10}+1\dfrac{5}{100}$
Convert to hundredths:
$\dfrac{3}{10}=\dfrac{30}{100}$
Therefore, $2\dfrac{30}{100}+1\dfrac{5}{100}$ $=3\dfrac{35}{100}$ $=3.35$

Arrange in ascending order: $9.2,\;1.99,\;9.14,\;1.5$.
Answer:Write the decimals with the same number of decimal places:
$9.2=9.20$
$1.5=1.50$
Compare the numbers:
$1.50<1.99<9.14<9.20$
Therefore, the ascending order is: $1.5,\;1.99,\;9.14,\;9.2$
$\dfrac{22}{100}+\dfrac{3}{10}=$ ..............
Answer:Convert $\dfrac{3}{10}$ to hundredths: $\dfrac{3}{10}=\dfrac{30}{100}$
So, $\dfrac{22}{100}+\dfrac{30}{100}$ $=\dfrac{52}{100}$ $=0.52$
Find the result of: $\dfrac{43}{100}+\dfrac{3}{10}=$ ..............
Answer:$\dfrac{43}{100}+\dfrac{3}{10}$
Convert $\dfrac{3}{10}$ to hundredths: $\dfrac{3}{10}=\dfrac{30}{100}$
So, $\dfrac{43}{100}+\dfrac{30}{100}$ $=\dfrac{73}{100}$ $=0.73$
Find the result of: $1\dfrac{53}{100}+2\dfrac{3}{10}=$ ..............
Answer:$1\dfrac{53}{100}+2\dfrac{3}{10}$
Convert $\dfrac{3}{10}$ to hundredths: $\dfrac{3}{10}=\dfrac{30}{100}$
