How to solve
This quiz mixes questions from different lessons, like a real test. Read each question carefully: the lesson name in front tells you what kind of problem it is. Check your answers, then practise the lessons where you made mistakes.
Example
Adding Decimals on a Number Line: 0.3 + 0.6 = ___
Answer: 0.9

💡 How to solve: Adding & Subtracting Decimals (Mixed Review)
Line up the decimal points, adding zeros so both numbers have the same number of digits after the point. Add or subtract like whole numbers, then put the decimal point straight down in the answer.

💡 How to solve: Subtracting Decimals Using Expanded Form on a Number Line
Write the number you are taking away in expanded form, then take away one part at a time on the number line. Example: 2.7 − 1.4. In expanded form 1.4 = 1 + 0.4. Start at 2.7, jump back 1 to land on 1.7, then jump back 0.4 to land on 1.3. So 2.7 − 1.4 = 1.3. With hundredths there can be three jumps: 3.85 − 1.32 → 1.32 = 1 + 0.3 + 0.02, so 3.85 → 2.85 → 2.55 → 2.53. If a jump passes a whole number, keep counting back past it: 4.2 − 0.7 → 4.2 back 0.2 is 4.0, then 0.5 more is 3.5.

💡 How to solve: Adding Decimals with Bar Charts
Read the number at the top of each bar to find its value. To add decimals, line up the decimal points and add each place from right to left, just like whole numbers. For example, if the chart shows Mon = 1.4 km and Tue = 2.3 km, add: 1.4 + 2.3 = 3.7 km.

💡 How to solve: Adding Decimals (Tenths & Hundredths)
Line up the decimal points so tenths are under tenths and hundredths under hundredths, then add from the right just like whole numbers, carrying when a column makes 10 or more. Put the decimal point in the answer straight below the others. Example: 2.35 + 1.48: 5 + 8 = 13, write 3 carry 1; 3 + 4 + 1 = 8; 2 + 1 = 3, so the sum is 3.83. If the places are different, write a zero to fill the gap: 3.4 + 2.57 = 3.40 + 2.57 = 5.97. A whole number has its decimal point at the end: 5 + 2.37 = 5.00 + 2.37 = 7.37.

💡 How to solve: Subtracting Decimals (Tenths & Hundredths)
Line up the decimal points, then subtract from the right just like whole numbers, borrowing when the top digit is smaller. Put the decimal point in the answer straight below the others. Example: 6.42 − 2.75: 2 is less than 5, so borrow: 12 − 5 = 7; 3 is less than 7, so borrow again: 13 − 7 = 6; 5 − 2 = 3. The difference is 3.67. If the places are different, write zeros to fill the gaps: 5.6 − 2.38 = 5.60 − 2.38 = 3.22, and 5 − 2.37 = 5.00 − 2.37 = 2.63.

💡 How to solve: Introduction to Decimals
The first digit after the decimal point is tenths and the second is hundredths, so 3 tenths and 4 hundredths is 0.34. To compare decimals, compare the whole numbers first, then the tenths, then the hundredths. Use <, > or =.

💡 How to solve: Adding Decimals on a Number Line
Start at the first number on the number line. Count forward by the amount you are adding. The spot where you land is the sum. Example: 0.3 + 0.5 — start at 0.3, jump 0.5 to the right, and land on 0.8. When the jump crosses a whole number (like 0.7 + 0.6), keep counting past 1.0 to land on 1.3.
