When there are no special grouping symbols, math problems are solved from left to right. Although there are other important rules about the order in which you do the operations (addition/subtraction/multiplication/division) in a math expression or equation, this lesson will focus on grouping symbols. The rest of the order of operations rules will be explained in the Determining Order of Operations lesson. To help prevent confusion as you learn how to use the grouping symbols, this lesson will only use addition and subtraction.
Answer:
The numerator signifies the number to be divided by the denominator, and also represents the total number of parts taken into account.
The correct answer is She have left $7.5 after buying the coat and skirt.
Step-by-step explanation
This question is incomplete, the complete question is:
Mary had $60 and spent 0.75 o 3/4 of it on a coat. She then bought a skirt with 50% of the money that she had left. How much money did she have left after buying the coat and skirt?
The answer is $7.50
Explanation:
To know how much money Mary has left after buying the coat we have to multiply $60 by 0.75 as this would help us know the price of the coat.
60 x 0.75 = 45 (price of the coat)
Then we have to subtract 45 from 60 to know how much money she have left after buying the coat.
60 -45 = 15 (Money left)
Then she bought a skirt with 50% of the money that she had left. To know how much money costs the skirt we have to multiply 15 by 0.50. The result of this operation is $7.5, and finally, we have to subtract again $7.5 that she spent on her skirt from $15 and the final result is $7.5
