Step-by-step explanation:

Maddison hid 12 of her sister's birthday gifts around the house. If this was 15% of the gifts, how many total gifts did her sister have?

Let the Total gifts that her sister has be represented by x

Hence:

15% of x = 12

15/100 × x = 12

15x /100 = 12

Cross Multiply

15x = 100 × 12

15x = 1200

x = 1200/15

x = 80 gifts

Hence, the total gifts her sister has is 80 gifts

80 total gifts

Step-by-step explanation:

Step one:

given data

Maddison hid 12 of her sister's birthday gifts

we are told that 12 gift is 15% of the total gifts

let the total gifts be x

so

=15/100*x= 12

=0.15x= 12

divide both sides by 0.15

x= 12/0.15

x=80 total gifts
