Answer 1

All you have to do is plug in the given values for a and b.

0.9a - 1.5b = ?

a = 15
b = 3

0.9 (15) - 1.5 (3)

= 13.5 - 4.5

= 9

Note:

•Integers are whole numbers.
For ex: 1, 2, 3, 4...

•Decimals have a period in between 2 numbers
For ex: 0.1, 0.2, 0.3

Sometimes when it’s concerning significant digits then decimals could also be
1.0, 2.0, 3.0 ... I wouldn’t worry about this right now until you get into higher years
