E: CONTENT
Revision of Multiplication and Division
24 × 5 = 120
120 ÷ 5 = 24
Revision of Squares and Square Roots
6² = 36
√36 = 6
Revision of Multiples and LCM
Multiples of 3:
3, 6, 9, 12, 15…
Multiples of 4:
4, 8, 12, 16…
Therefore:
LCM of 3 and 4 = 12
Revision of Factors and HCF
Factors of 8:
1, 2, 4, 8
Factors of 12:
1, 2, 3, 4, 6, 12
Therefore:
HCF of 8 and 12 = 4
Revision of Estimation
47 ≈ 50 to the nearest ten.
263 ≈ 300 to the nearest hundred.
Revision of Money
₦500 + ₦250 = ₦750
₦1,000 – ₦650 = ₦350
Revision of Profit and Loss
CP = ₦800
SP = ₦1,000
Profit:
₦1,000 – ₦800 = ₦200
Revision of Open Sentences
5 + □ = 12
□ = 7
