4) 3/10. To add fractions, find a common denominator. The least common multiple of 5 and 10 is 10. Convert 1/5 to 2/10. Then, 2/10 + 1/10 = 3/10.

1) 1/3. To subtract fractions, find a common denominator. The least common multiple of 3 and 9 is 9. Convert 2/3 to 6/9. Then, 6/9 - 3/9 = 3/9. Simplify 3/9 by dividing both numerator and denominator by 3, which gives 1/3.

Q: Susan has 72 pencils. She wants to pack them equally into 8 goodie bags. How many pencils are there in one bag?

2) 9. To find the number of pencils in one bag, divide the total number of pencils by the number of bags: 72 ÷ 8 = 9 pencils.

Q: 1/4 = ____/12 What is the missing number in the box?

3) 3. To make the denominators equal, multiply the denominator of 1/4 by 3 (4 × 3 = 12). To keep the fraction equivalent, multiply the numerator by the same number: 1 × 3 = 3. So, the missing number is 3.

Q: Arrange the following numbers from the greatest to the smallest. 6507, 6057, 6705 (greatest) ____ (smallest)

4) 6705, 6507, 6057. Compare the numbers by looking at their digits from left to right. All numbers have 6 in the thousands place. In the hundreds place, 6705 has 7, 6507 has 5, and 6057 has 0. So, 6705 is the greatest. Comparing 6507 and 6057, 6507 is greater. Thus, the order from greatest to smallest is 6705, 6507, 6057.

Q: Ms Chong baked 498 cookies. She ate 6 cookies and gave 60 cookies to her friends. How many cookies were left?

1) 432. Start with the total number of cookies: 498. Subtract the cookies she ate: 498 - 6 = 492. Then, subtract the cookies she gave to friends: 492 - 60 = 432 cookies.

Q: What does ☆ represent?

3) 3. This is a multiplication problem. In the tens column, (☆ × 4) + 2 (carried over from 6 × 4 = 24) must result in a number whose ones digit is 4. Trying the options: if ☆ = 3, then (3 × 4) + 2 = 12 + 2 = 14. This matches the 4 in the tens place and carries over 1 to the hundreds place. Then, (2 × 4) + 1 (carried over) = 8 + 1 = 9, which matches the hundreds place.

Q: How many minutes are there in 2 h 38 min?

3) 158. There are 60 minutes in 1 hour. So, in 2 hours, there are 2 × 60 = 120 minutes. Add the remaining 38 minutes: 120 + 38 = 158 minutes.
