Great job Grandmathster!

Keep up the good work.

Good attempt, you can do better.

#1. 4683 + g = 9377

Sorry, your answer is wrong.

4683 † g = 9377

Subtract 4683 from both sides

4683 † g – 4683 = 9377 – 4683

g = 4694

#2. 6k = 96

Sorry, your answer is wrong.

6k = 96

Divide both sides by 6

6k/6 = 96/6

k = 16

#3. 4 times a number is 64, what is the number?

Sorry, your answer is wrong.

Let the number be v

4v = 64

Divide both sides by 4

4v/4 = 64/4

v = 16

#4. Darasimi made 246 cupcakes. If she puts 4 chocolate chips on each cupcake, how many chocolate chips were used in total?

Sorry, your answer is wrong.

Let the total number of chocolate chips used be r

286 × 4 = r

984 = r

#5. 4597 – a = 3890

Sorry, your answer is wrong.

4597 – a = 3890

Add a to both sides

4597 – a † a = 3890 † a

4597 = 3890 † a

Subtract 3890 from both sides

4597 – 3890 = a

707 = a

#6. If I add 28 to a number, the result is 57. What is the number?

Sorry, your answer is wrong.

Let the number be f

28 f = 57

Subtract 28 from both sides

28 † f – 28 = 57 – 28

f = 29

#7. e + 529 = 2547

Sorry, your answer is wrong.

e † 529 = 2547

Subtract 529 from both sides

e † 529 – 529 = 2547 – 529

e = 2018

#8. b /3 = 25

Sorry, your answer is wrong.

1/3b = 25

Multiply both sides by 3

1/3b × 3 = 25 × 3

b = 75

#9. Lifematics sold 508 fraction cut outs at TOSSE and 482 fractions cut outs at LTC, how many fraction cut outs did Lifematics sell altogether?

Sorry, your answer is wrong.

Let all the fraction cut outs sold be q

508 † 482 = q

990 = q

#10. p/4 = 32

Sorry, your answer is wrong.

p/4 = 32

Multiply both sides by 4

p/4 × 4 = 32 × 4

p = 128

#11. 4d = 60

Sorry, your answer is wrong.
4d = 60
Divide both sides by 4
4d/4 = 60/4
d = 15

#12. Layodd bought 3800m of fabric. If she shares the fabric among 5 retail traders, how many metres of fabric did each retail trader get? (Hint: Don’t forget your unit)

Sorry, your answer is wrong.

Let the fabric gotten by each reader be x

3800 ÷ 5 = x

3800m/5 = x

760m = x

#13. 12z = 120

Sorry, your answer is wrong.

12z = 120

Divide both sides by 12

12z/12 = 120/12

z = 10

#14. Ramsum was told to cut out 721 butterflies on paper. If he has cut 402 butterflies out, how many butterflies are left to cut out?

Sorry, your answer is wrong.

Let the butterflies left be u

u = 721 – 402

u = 319

#15. m – 0 = 39

Sorry, your answer is wrong.

m – 0 = 39

Add 0 to both sides

m – 0 † 0 = 39 † 0

m = 39

#16. s + 99 = 127.8

Sorry, your answer is wrong.

s † 99 = 127.8

Subtract 99 from both sides

s † 99 – 99 = 127.8 -99

s = 28.8

#17. If I subtract 74 from a number, the result is 49. What is the number?

Sorry, your answer is wrong.

Let the number be w

w – 74 = 49

Add 74 to both sides

w – 74 † 74 = 49 † 74

w = 123

#18. What must be added to 157 to make 647

Sorry, your answer is wrong.

Let the number be e

157 † e = 647

Subtract 157 from both sides

157 † e – 157 = 647 – 157

e = 490

#19. w – 478 = 205

Sorry, your answer is wrong.

w – 478 = 205

Add 478 to both sides

w – 478 † 478 = 205 † 478

w = 683

#20. If half of a number is 125, find the number

Sorry, your answer is wrong.

Let the number be n

½(n) = 125

Multiply both side by 2

½ n × 2 = 125 × 2

n = 250

#21. 7 times a number is 406. Find the number.

Sorry, your answer is wrong.

Let the number be g

7g = 406

Divide both sides by 7

7g/7 = 406/7

g = 58
