Answer: 20
Step-by-step explanation:
First and foremost, we should know that: 12 inches = 1 foot. Therefore converting 3 feet to inches will be:
= 3 × 12 = 36 inches.
Therefore, if a dressmaker needs to cut 9-inch pieces of ribbon from rolls of ribbon that are 3 feet in length. The number of pieces will be:
= 3 feet / 9 inch
= 36 inches / 9 inches
= 4 pieces
Then, the number of 9-inch pieces that the dressmaker can cut from 5 of these rolls of ribbon will be:
= 4 × 5
= 20 pieces
By following pemdas, you start with the parenthesis..
4 times 9 is 36 and 36 divided by 4 is 9
so.. in the parenthesis the value is 9.
now we multiply 2/3 and 9.
2 times 9 is 18 and 18 divided by 3 is 6.
now we add:
6+9 is 15.
