Explanation:
1. let the percentage be x
therefore, x% of 126=22
(x/100) * 126=22
x=(22*100)/126
=17.46%
2. let percentage be x
25.7=x% of 141
25.7=(x/100)*141
x=(25.7*100)/141
x=18.23%
3. 46=x% of 107
46=(x/100)*107
x=(46*100)/107
x=43%
4. 62% of x=89.3
(62/100)*x=89.3
x=(89.3*100)/62
x=144
5. 30% of 117=x
( 30/100)*117=35.1
6. 120% of 118=?
(120/100)*118=141.6
7. 270 of 60
270*60= 16200
8. 87% of 41
(87/100)*41
=35.67
9. x% of 88.6=70
(x/100)*88.6=70
x=(70*100)/88.6
x=79%
