Good attempt, you can do better.
#1. 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
#2. e + 529 = 2547
Sorry, your answer is wrong.
e † 529 = 2547
Subtract 529 from both sides
e † 529 – 529 = 2547 – 529
e = 2018
#3. 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
#4. 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
#5. 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
#6. 4683 + g = 9377
Sorry, your answer is wrong.
4683 † g = 9377
Subtract 4683 from both sides
4683 † g – 4683 = 9377 – 4683
g = 4694
#7. 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
#8. 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
#9. 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
#10. 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
#11. b /3 = 25
Sorry, your answer is wrong.
1/3b = 25
Multiply both sides by 3
1/3b × 3 = 25 × 3
b = 75
#12. w – 478 = 205
Sorry, your answer is wrong.
w – 478 = 205
Add 478 to both sides
w – 478 † 478 = 205 † 478
w = 683
#13. 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
#14. 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
#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. 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
#17. 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
#18. p/4 = 32
Sorry, your answer is wrong.
p/4 = 32
Multiply both sides by 4
p/4 × 4 = 32 × 4
p = 128
#19. 6k = 96
Sorry, your answer is wrong.
6k = 96
Divide both sides by 6
6k/6 = 96/6
k = 16
#20. 4d = 60
Sorry, your answer is wrong.
4d = 60
Divide both sides by 4
4d/4 = 60/4
d = 15
#21. 12z = 120
Sorry, your answer is wrong.
12z = 120
Divide both sides by 12
12z/12 = 120/12
z = 10
