Q1. b) 3.5
Explanation: Three and five tenths means 3 whole parts and 5 tenths, which is written as 3.5.
Q2. c) Tenths
Explanation: In a decimal number, the digit immediately after the decimal point is in the tenths place. So 7 in 4.7 is in the tenths place.
Q3. c) 0.6
Explanation: 6/10 means 6 tenths, which is written as 0.6 in decimal form.
Q4. a) 3.7
Explanation: Adding the whole parts 2 + 1 = 3, and adding the tenths 0.3 + 0.4 = 0.7, so 2.3 + 1.4 = 3.7.
Q5. b) 0.9
Explanation: Comparing tenths digits, 9 is the largest among 3, 9, 5, and 7. So 0.9 is the greatest.
Q6. whole
Explanation: The decimal point separates the whole number part from the fractional part.
Q7. tenths
Explanation: In 5.8, the digit after the decimal point is 8, and it sits in the tenths place.
Q8. 0.3
Explanation: 3 divided by 10 gives 3 tenths, written as 0.3 in decimal notation.
Q9. 2.2
Explanation: 4.5 - 2.3 = 2.2. Subtract tenths: 5 - 3 = 2, and subtract ones: 4 - 2 = 2.
Q10. decimal
Explanation: A number with one digit after the decimal point is said to have one decimal place.
Q11. a) 7/10 = 0.7
b) 2/10 = 0.2
Explanation: Fractions with denominator 10 are written directly as one digit after the decimal point.
Q12. 3.5 - 1.2 = 2.3 metres
Explanation: Subtract tenths: 5 - 2 = 3, and subtract ones: 3 - 1 = 2. So 2.3 metres of ribbon is left.
Q13. Whole number part of 8.6 is 8.
Decimal part of 8.6 is 0.6 or .6.
Explanation: The digits before the decimal point form the whole number part and the digits after the decimal point form the decimal part.
Q14. Increasing order: 0.1, 0.4, 0.5, 0.8
Explanation: Compare the tenths digits. 1 is smallest, then 4, then 5, then 8 is the largest. So the order from smallest to greatest is 0.1, 0.4, 0.5, 0.8.
Q15. One acceptable answer: 0.4 + 0.6 = 1.0
Other acceptable answers include: 0.3 + 0.7 = 1.0, or 0.5 + 0.5 = 1.0, or 0.2 + 0.8 = 1.0.
