Answer:

1. a. (9/50) X 100= 9X2 = 18%

b. (36/250) X 100 = (36/ 10) X 4 = 14.4%

Step-by-step explanation:

5. marks scored= 79% of 600

= (79/100) x 600

= 79 x 6= 474

6. Percentage of girls = (15/75) x 100

= (15/3) x 4

= 5 x 4= 20%

7. Money spent = (35%+25%+5%) of 600

= (65% of 600)

= (65/100) x 600

= 65 x 6= 390

8. Pages left = 70% of 800

= (70/100) x 800

= 70 x 8= 560
