Q1: Each batch of cookie mix needs 0.4 cups of sugar, and each batch can make 16 cookies. If Ashley is making 4 batches of cookies, how much sugar does she need?
Ans: 0.4 × 4 = 1.6
Therefore, she needs 1.6 cups of sugar.
Q2: Ashley measured 1.43 cups of sugar. How much more sugar does she need?
Ans: Required - Measured = Additional needed
1.60 - 1.43 = 0.17
She needs 0.17 cups more sugar.
Q3: After she finished making the cookies, Ashley had 0.945 kg of flour left. How much flour did she use?
Ans: Initial flour - Remaining flour = Flour used
2.64 - 0.945 = 1.695 kg
She used 1.695 kg of flour.
Q4: Ashley found 2 boxes of sugar in the kitchen. The green box is 1.26 kg, and the red box is 1.026 kg. Which box contains more sugar?
Ans: Compare the amounts by writing with the same number of decimal places:
1.260 kg > 1.026 kg
So, the green box contains more sugar.
Q5: She has 3 bags of flour. She has two smaller bags with 0.75 kg of flour each and a bigger bag which has 1.14 kg. How much flour does she have in total?
Ans: Add the two smaller bags first: 0.75 + 0.75 = 1.50 kg
Now add the bigger bag: 1.50 + 1.14 = 2.64 kg
She has 2.64 kg of flour in total.
Q6: Each batch of cookies is 8.9 oz. What is the weight of 2.5 batches of cookies?
Ans:8.9 × 2.5 = 22.25 oz
The weight of 2.5 batches of cookies is 22.25 oz.
Q7: Write the smallest and greatest 6-digit numbers formed by using digits 1,0,5,7 with repetition.
Ans: To make the greatest 6-digit number, use the largest digit (7) in every place: 777777 → 7,77,777 (Indian grouping).
To make the smallest 6-digit number, the first digit cannot be 0, so use 1 followed by zeros: 100000 → 1,00,000.
Greatest 6-digit number with repetition = 7,77,777
Smallest 6-digit number with repetition = 1,00,000
Q8: The difference between the two numbers is 3856749. If the smaller number is 2565638. Find the greater number.
Ans: Greater number = Smaller number + Difference
3,856,749 + 2,565,638 = 6,422,387
So, the greater number is 6,422,387 (written as 64,22,387 in Indian grouping).
Q9: A thread of length 20m has been divided into 5 pieces. What is the length of each piece?
Ans: Total length ÷ Number of pieces = Length of each piece
20 ÷ 5 = 4 m
Each piece is 4 m long.
Q10: Arrange in descending order 4123676,71204381,176489,3240973
Ans: Count digits to compare sizes:
4123676 → 7 digits
71204381 → 8 digits
176489 → 6 digits
3240973 → 7 digits
Numbers with more digits are larger, so descending order from largest to smallest is:
71204381, 4123676, 3240973, 176489.
Q11: The mass of a bag is 2kg 890g. What is the mass of 14 such bags?
Ans: Convert to grams: 2 kg 890 g = 2,890 g
Total mass in grams = 2,890 × 14 = 40,460 g
Convert back to kg and g: 40,460 g = 40 kg 460 g
So, mass of 14 bags = 40 kg 460 g.
Q12: A man had Rs. 2,08,78,560 amounts in his bank. He withdrew Rs. 48,36,980 in the month of January, Rs. 3,95,648 in the month of February and Rs. 45,000 in the month of March. What is the amount remaining in his bank account by the end of March?
Ans:Total amount = Rs. 2,08,78,560
After January withdrawal: 2,08,78,560 - 48,36,980 = 1,60,41,580
After February withdrawal: 1,60,41,580 - 3,95,648 = 1,56,45,932
After March withdrawal: 1,56,45,932 - 45,000 = 1,56,00,932
Amount remaining by the end of March = Rs. 1,56,00,932.
