Here are the step-by-step solutions for each problem on the worksheet.
1. John and Petra’s Toys
* First, find out how many toys they have together: $50 + 38 = 88$ toys.
* Next, subtract the toys they took to the sale: $88 - 23 = 65$.
* They have
65 toys left.
2. Netball Goals
* Add the goals from the first match: $16 + 12 = 28$ goals.
* Add the goals from the second match: $18 + 15 = 33$ goals.
* Add the totals from both matches together: $28 + 33 = 61$.
* They scored
61 goals altogether.
3. The Mystery Number
* Work backward from the answer (29).
* The last step was adding 7, so subtract 7: $29 - 7 = 22$.
* The step before that was doubling the number, so divide by 2: $22 \div 2 = 11$.
* The number you began with is
11.
4. Boxes of Biscuits
* Calculate the biscuits in the four boxes: $4 \times 30 = 120$ biscuits.
* Add the biscuits from the other box: $120 + 27 = 147$.
* There are
147 biscuits altogether.
5. Pocket Money
* Michael and Samantha have 60p each: $60 + 60 = 120$p.
* Toni and John have 70p each: $70 + 70 = 140$p.
* Add them all together: $120 + 140 = 260$p.
* This is equal to
£2.60 (or 260p).
6. Books on Shelves
* Top shelf: 140 books.
* Two shelves below have 120 books *each*: $120 + 120 = 240$ books.
* Add the top shelf to the bottom shelves: $140 + 240 = 380$.
* There are
380 books altogether.
7. Rolls of Film
* Three rolls take 24 photos each: $3 \times 24 = 72$ photos.
* Four rolls take 36 photos each: $4 \times 36 = 144$ photos.
* Add the two totals together: $72 + 144 = 216$.
* They can take
216 photographs in total.
8. Marbles (Boys vs Girls)
* Boys' marbles: $16 \text{ boys} \times 10 \text{ marbles} = 160$ marbles.
* Girls' marbles: $15 \text{ girls} \times 8 \text{ marbles} = 120$ marbles.
* Find the difference: $160 - 120 = 40$.
* The boys have
40 more marbles than the girls.

3. 11
