Answer:
Step-by-step explanation:
(i) HCF of 24 and 40 is 8.
∴ 24 : 40 = 2440= 24 ÷ 840 ÷ 8= 35 = 3 : 5
Hence, 24 : 40 in its simplest form is 3 : 5.
(ii) HCF of 13.5 and 15 is 1.5.
13.515=135150The HCF of 135 and 150 is 15.=135 ÷ 15150 ÷ 15=910
Hence, 13.5 : 15 in its simplest form is 9 : 10.
(iii) 203 : 152=40 : 45
The HCF of 40 and 45 is 5.
∴ 40 : 45 = 4045=40 ÷ 545 ÷ 5=89 = 8 : 9
Hence, 623 : 712 in its simplest form is 8 : 9
(iv) 9 : 6
The HCF of 9 and 6 is 3.
∴ 9 : 6 =
