5. Simplify and find the ratio
Penjelasan dengan langkah-langkah:
Simplify →Menyederhanakan
6)a:b:c =75:120:132
a)Simplify a:b:c
menyederhanakan a:b:c
=75:120:132
=(75/3):(120/3):(132:3)
=25:40:44
b)find b:a
=40:25
= 8:5
c)find b:c
=40:44
=10:11
Jawab:
(6)
(i) = 25 : 40 : 44
(ii) b : a = 8 : 5
(iii) b : c = 10 : 11
(7)
(a) = 16 : 36 : 15
(c) = 11 : 21 : 60
Penjelasan dengan langkah-langkah:
(6) Divide these terms by their GCF
(i) 75 : 120 : 132 (divisible by 3)
... (:3) (:3) (:3)
= 25 : 40 : 44
... a b c
(ii) b : a = 40 : 25 (divisible by 5)
... (:5) (:5)
... b : a = 8 : 5
(iii) b : c = 40 : 44 (divisible by 4)
... (:4) (:4)
... b : c = 10 : 11
(7) Simplification of ratios
(a) (2/3) : (3/2) : (5/8)
Find the LCM of the denominators
of each term.
LCM of 3, 2 and 8 = 2·3·2² = 24
Then multiply the LCM by each term.
.. (2/3)·24 : (3/2)·24 : (5/8)·24
= 2 · 8 : 3 · 12 : 5 · 3
= 16 : 36 : 15
(c) 0.33 : 0.63 : 1.8
= 0.33(100) : 0.63(100) : 1.8(100)
= 33 : 63 : 180 (divisible by 3)
.. (:3) (:3) (:3)
= 11 : 21 : 60

6. Expand, simplify, and then factorise the expression (3 – h)^2 -(h-3)(h+1)
[tex](3 - h)^{2} - (h - 3)(h + 1) \\ = {(3 - h)}^{2} + (3 - h)(h + 1) \\ = (3 - h)((3 - h) +( h + 1)) \\ = (3 - h)(4) \\ = 12 - 4h[/tex]
the answer is written above.
7. Expand and simplify the following expressions :7 (h + 5) −(h−3)=
Penjelasan dengan langkah-langkah:
7(h + 5) − (h − 3)
= 7h + 7.5 - h + 3
= 7h + 35 - h + 3
= 7h - h + 35 + 3
= (7 - 1)h + (35 + 3)
= 6h + 38
