Hey mate
Step-by-step explanation:
Q6 . Express the following as decimals and percentages.
1 ) 1 : 2
= 1 / 2
= 1 / 2 * 100 ( Cut 100 / 2 = 50 )
= 1 * 50
= 50 %
= 1 : 2
= 1 / 2 * 2 / 50
= 2 / 100
= 0.02
2 ) 3 by 5
= 3 / 5
= 3 / 5 * 100 ( Cut 100 / 5 = 20 )
= 3 * 20
= 60
= 3 / 5
= 3 / 5 * 2 / 2
= 6 / 10
= 0.6
3 ) 19 : 40
= 19 : 40
= 19 / 40 * 100
= 152 / 2
= 76 %
= 19 : 40
= 19 / 40 * 25 / 25
= 475 / 1000
= 0.475
