dude its just 3 rooms. yes

3 rooms

Step-by-step explanation:

For 1 1/4 rolls of electric wire = 1 room

For 3 3/4 rolls of electric wire = 3 3/4 ÷ 1 1/4

                                                 = 15/4 ÷ 5/4

                                                 = 15/4 x 4/5

                                                 = 15/5

                                                 = 3 rooms

The steps for calculating the prime factors of a number is similar to the process of finding the factors of any number.
Start dividing the number by the smallest prime number i.e., 2, followed by 3, 5, and so on to find the smallest prime factor of the number.
Again, divide the quotient by the smallest prime number
