Mathematics

When you have problems like this, you NEED to use the order of operations, or PEMDAS.

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

As you can see from the list, multiplication comes first. 3x100 = 300

300x1=300

And lastly, addition

300+7=307

PLEASE KNOW: Multiplication/Division are done depending which comes first in the problem, the same applies to Addition/Subtraction

attashe74 [19]

Answer:

4.86

Step-by-step explanation:

Melanie uses 8.1 pints of blue paint and white paint for her bedroom

2/5 of this amount is blue paint

Therefore the amount of white paint can be calculated as follows

= 2/5

= 0.4×100

= 40%

60/100 × 8.1

= 0.6 × 8.1

= 4.86

Hence 4.86 pints of white paint will be used to paint the bedroom
